South Lyon United's Radcliffe Approaching Milestone Win, Another History-Making Moment

Originally, Deanna Radcliffe got into coaching lacrosse simply because it was a nice summer job.

Greater DetroitFrom that simple beginning, Radcliffe is now on the verge of making high school sports history within the state of Michigan.

No girls or boys lacrosse coach has reached 300 career victories since the sport became MHSAA-sponsored in 2005. But Radcliffe is oh-so-close. Following a win over Haslett on Wednesday, Radcliffe has 299 career victories. 

The milestone 300th win likely will come Saturday when South Lyon United plays in a tournament at Saline. 

In order to get their names etched in the record book, any high school coach in Michigan has had to reach at least 300 wins since the MHSAA brought the sport into its championship lineup. So Radcliffe is literally about to become the first and only coach in the MHSAA coaching records for lacrosse. 

Radcliffe is in her 10th season coaching for South Lyon Unified and also coached at Hartland from 2013 to 2022. This is actually her second stint at South Lyon, where she spent seven years as head coach before taking the Hartland job. 

“It just means I’ve been doing this for a long time,” Radcliffe said. “What it really represents to me is all the players, coaches and families I’ve had the opportunity to coach. I’ve been fortunate to coach in an area that was willing to embrace the sport. I have been able to catch some really great teams and athletes across all levels from youth to high school and even collegiately. That’s the part that means the most, those relationships and experiences. The wins are just a byproduct of that.”

Radcliffe got her start in lacrosse very young, saying she picked up the game at 3-4 years old while growing up in Pennsylvania. She was introduced to the game by her aunt.

Radcliffe eventually became good enough as a player to earn a college opportunity, ultimately being named the Atlantic 10 Offensive Player of the Year in 2003 while playing for Temple. 

Radcliffe eventually started a career as a special education teacher and was a high school coach in Pennsylvania before moving to Michigan in 2006, where she has coached club, high school and even college lacrosse as she spent time as an assistant at Cleary University. 

“I just enjoyed being around the game and the competitive environment, so I kept doing it,” Radcliffe said of what has kept her coaching. “Over time, it stopped being something I was just doing in the summers and became something I really valued and stayed connected to. It’s grown naturally from there, and I’ve been fortunate to continue coaching while also working in education.” 

The most noteworthy win of her career came last June, when South Lyon Unified earned a 6-3 Division 1-clinching victory over Hartland to give Radcliffe her first MHSAA Finals championship as head coach in a matchup between the two programs she built up. 

South Lyon Unified is 18-0 this season and has won 39 straight games going back to last spring's opener. 

“She has so much knowledge of the sport and really cares for each and every one of us,” said South Lyon United senior captain Teagan Wesner. “Deanna has been one of the best coaches I have ever had, and I am extremely grateful to have had the opportunity to play for her. I am very happy for Deanna, and I am excited to be a part of the team who helped her reach 300 wins.” 

When Radcliffe first arrived in Michigan, lacrosse was in its first years as a sanctioned sport by the MHSAA. Now, she has seen it grow by leaps and bounds. 

“One of the most rewarding parts has been seeing the long-term impact,” she said. “Many of the players I once coached are now youth, high school or college coaches themselves. Some are officials, and some I’m even coaching against or alongside now. That’s been incredibly meaningful and really speaks to the strength of the community the sport has built.”

Health & Safety: A Look Back, Gallop Ahead

By John E. (Jack) Roberts
MHSAA Executive Director, 1986-2018

August 7, 2015

We are just completing year six of eight during which we have been addressing the four important health and safety issues that, for ease of conversation, we call the “Four Hs.”

During the 2009-10 and 2010-11 school years, our focus was on Health Histories. We made enhancements in the pre-participation physical examination form, stressing the student’s health history, which we believe was and is the essential first step to participant health and safety.

During the 2011-12 and 2012-13 school years, our focus was on Heads. We were an early adopter of removal-from-play and return-to-play protocols, and our preseason rules/risk management meetings for coaches included information on concussion prevention, recognition and aftercare.

Without leaving that behind, during the 2013-14 and 2014-15 school years, our focus was on Heat – acclimatization. We adopted a policy to manage heat and humidity – it is recommended for regular season and it’s a requirement for MHSAA tournaments. The rules/risk management meetings for coaches during these years focused on heat and humidity management.

At the mid-point of this two-year period, the MHSAA adopted policies to enhance acclimatization at early season practices and to reduce head contact at football practices all season long.

Without leaving any of the three previous health and safety “H’s” behind, during the 2015-16 and 2016-17 school years, our focus will be on Hearts – sudden cardiac arrest and sudden cardiac death.

Coinciding with this emphasis is the requirement that all high school level, varsity level head coaches be CPR certified starting this fall. Our emphasis will be on AEDs and emergency action plans – having them and rehearsing them.

On Feb. 10, bills were introduced into both the U.S. Senate and House of Representatives, together called the “Safe Play Act (see below),” which addressed three of the four health and safety “H’s” just described: Heat, Hearts and Heads.

For each of these topics, the federal legislation would mandate that the director of the Centers for Disease Control develop educational material and that each state disseminate that material.

For the heat and humidity management topic, the legislation states that schools will be required to adopt policies very much like the “MHSAA Model Policy to Manage Heat and Humidity” which the MHSAA adopted in March of 2013.

For both the heart and heat topics, schools will be required to have and to practice emergency action plans like we have been promoting in the past and distributed to schools this summer.

For the head section, the legislation would amend Title IX of the 1972 Education Amendments and eliminate federal funding to states and schools which fail to educate their constituents or fail to support students who are recovering from concussions. This support would require multi-disciplinary concussion management teams that would include medical personnel, parents and others to provide academic accommodations for students recovering from concussions that are similar to the accommodations that are already required of schools for students with disabilities or handicaps.

This legislation would require return-to-play protocols similar to what we have in Michigan, and the legislation would also require reporting and recordkeeping that is beyond what occurs in most places.

This proposed federal legislation demonstrates two things. First, that we have been on target in Michigan with our four Hs – it’s like they read our playbook of priorities before drafting this federal legislation.

This proposed federal legislation also demonstrates that we still have some work to do.

And what will the following two years – 2017-18 and 2018-19 – bring? Here are some aspirations – some predictions, but not quite promises – of where we will be.

First, we will have circled back to the first “H” – Health Histories – and be well on our way to universal use of paperless pre-participation physical examination forms and records.

Second, we will have made the immediate reporting and permanent recordkeeping of all head injury events routine business in Michigan school sports, for both practices and contests, in all sports and at all levels.

Third, we will have added objectivity and backbone to removal from play decisions for suspected concussions at both practices and events where medical personnel are not present; and we could be a part of pioneering “telemedicine” technology to make trained medical personnel available at every venue for every sport where it is missing today.

Fourth, we will have provided a safety net for families who are unable to afford no-deductible, no exclusion concussion care insurance that insists upon and pays for complete recovery from head injury symptoms before return to activity is permitted.

We should be able to do this, and more, without judicial threat or legislative mandate. We won’t wait for others to set the standards or appropriate the funds, but be there to welcome the requirements and resources when they finally arrive.

Safe Play Act — H.R.829
114th Congress (2015-2016) Introduced in House (02/10/2015)

Supporting Athletes, Families and Educators to Protect the Lives of Athletic Youth Act or the SAFE PLAY Act

Amends the Public Health Service Act to require the Centers for Disease Control and Prevention (CDC) to develop public education and awareness materials and resources concerning cardiac health, including:

 

  • information to increase education and awareness of high risk cardiac conditions and genetic heart rhythm abnormalities that may cause sudden cardiac arrest in children, adolescents, and young adults;
  • sudden cardiac arrest and cardiomyopathy risk assessment worksheets to increase awareness of warning signs of, and increase the likelihood of early detection and treatment of, life-threatening cardiac conditions;
  • training materials for emergency interventions and use of life-saving emergency equipment; and
  • recommendations for how schools, childcare centers, and local youth athletic organizations can develop and implement cardiac emergency response plans.

Requires the CDC to: (1) provide for dissemination of such information to school personnel, coaches, and families; and (2) develop data collection methods to determine the degree to which such persons have an understanding of cardiac issues.

Directs the Department of Health and Human Services to award grants to enable eligible local educational agencies (LEAs) and schools served by such LEAs to purchase AEDs and implement nationally recognized CPR and AED training courses.

Amends the Elementary and Secondary Education Act of 1965 to require a state, as a condition of receiving funds under such Act, to certify that it requires: (1) LEAs to implement a standard plan for concussion safety and management for public schools; (2) public schools to post information on the symptoms of, the risks posed by, and the actions a student should take in response to, a concussion; (3) public school personnel who suspect a student has sustained a concussion in a school-sponsored activity to notify the parents and prohibit the student from participating in such activity until they receive a written release from a health care professional; and (4) a public school's concussion management team to ensure that a student who has sustained a concussion is receiving appropriate academic supports.

Directs the National Oceanic and Atmospheric Administration to develop public education and awareness materials and resources to be disseminated to schools regarding risks from exposure to excessive heat and humidity and recommendations for how to avoid heat-related illness. Requires public schools to develop excessive heat action plans for school-sponsored athletic activities.

Requires the CDC to develop guidelines for the development of emergency action plans for youth athletics.

Authorizes the Food and Drug Administration to develop information about the ingredients used in energy drinks and their potential side effects, and recommend guidelines for the safe use of such drinks by youth, for dissemination to public schools.

Requires the CDC to: (1) expand, intensify, and coordinate its activities regarding cardiac conditions, concussions, and heat-related illnesses among youth athletes; and (2) report on fatalities and catastrophic injuries among youths participating in athletic activities.
