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.
From 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.
“It just became part of my life early on,” she said.
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.”

Representative Council Approves Limited Regional Seeding in Girls Lacrosse at Fall Meeting

The addition of limited seeding at the Regional level of the Girls Lacrosse Tournament headlined actions taken by the Representative Council of the Michigan High School Athletic Association during its Fall Meeting on Dec. 2 in East Lansing.
Generally, the Council takes only a few actions during its Fall Meeting, with topics often introduced for additional consideration and action during its meetings in winter and spring. This Fall Meeting saw the Council take only three actions, with additional discussion centered on topics expected to receive more specific consideration at MHSAA sport committee meetings this winter and the Council’s meetings in March and May.
The Council approved a Girls Lacrosse Committee proposal to seed the top two teams in every Regional, and place those top seeds on opposite sides of the bracket beginning with the 2023 season. The two teams to be seeded will be determined by using the MHSAA’s Michigan Power Ratings (MPR) formula, which takes into account success and strength of schedule and is used currently to provide seeding information in boys lacrosse, girls and boys basketball, girls and boys soccer, and ice hockey. Only the top two teams in girls lacrosse will be seeded and separated; the other teams in each Regional will be placed on their brackets by random draw.
The Council also approved a Boys Lacrosse Committee recommendation that will allow athletes to participate in up to five quarters per day between teams at multiple levels – for example, varsity and junior varsity – also beginning with the 2023 season. For boys lacrosse multi-team tournaments, if two school teams (for example, the varsity and junior varsity) are at the same event, athletes may play in no more halves or quarters than what is being played by the school’s highest-level team that day. (Example: if the varsity team is playing three 30-minute half games for a total of six halves, a player playing both varsity and JV on the same day can play in six total halves that day.) The “fifth quarter” rule, by allowing athletes to compete on two levels on the same day, is intended to help programs that are otherwise lacking enough participants to field teams at multiple levels.
Taking into account the wintery weather conditions experienced by athletes during the MHSAA alpine ski season, the Council approved a Sports Medicine Advisory Committee recommendation to adopt the “MHSAA Competition and Practice Guidelines for Cold Weather,” which are specific to alpine skiing. The guidelines include a windchill chart and cold standards for ambient temperature. This proposal also was supported by the Ski Committee and will go into effect for the 2022-23 season.
Remaining discussions focused on results from this fall’s Update Meeting survey completed by administrators during the MHSAA’s annual presentations across the state. The Council considered survey data including on questions related to the out-of-season travel rule. The Council also discussed results of a fall survey completed by member school athletic directors and head varsity football coaches concerning ongoing conversations about scheduling and playoff format. Following the Football Committee meeting in January 2023, an ad hoc committee comprised of members of the MHSAA staff, Representative Council, Michigan Interscholastic Athletic Administrators Association (MIAAA) and Michigan High School Football Coaches Association (MHSFCA) will be convened for further discussion on these topics, with their report to be provided to the Council during its March 2023 meeting.
The Fall Meeting saw the appointment of Westland John Glenn athletic director Jason Malloy for a first-two-year term to the 19-person Council, and the re-appointment of Bay City Western principal Judy Cox for a second two-year term. Malloy previously was appointed to finish a partial term as one of the two representatives of member junior high/middle schools.
The Council reelected Scott Grimes, superintendent for Grand Haven Area Public Schools, as its president; and Vic Michaels, director of physical education and athletics for the Archdiocese of Detroit, as secretary-treasurer. Brighton High School athletic director John Thompson was elected Council vice president.
The Representative Council is the legislative body of the MHSAA. All but five members are elected by member schools. Four members are appointed by the Council to facilitate representation of females and minorities, and the 19th position is occupied by the Superintendent of Public Instruction or designee.
The MHSAA is a private, not-for-profit corporation of voluntary membership by more than 1,500 public and private senior high schools and junior high/middle schools which exists to develop common rules for athletic eligibility and competition. No government funds or tax dollars support the MHSAA, which was the first such association nationally to not accept membership dues or tournament entry fees from schools. Member schools which enforce these rules are permitted to participate in MHSAA tournaments, which attract more than 1.3 million spectators each year.
