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.”

Program Priorities
January 10, 2014
Many school districts face more requests from their constituents for sports programs than they have the resources to accommodate, so they are forced to make very difficult decisions. For three decades, when I’ve been consulted, I have offered and stood by this advice.
First, I advance the premise that if the activity is educational, there is just as much potential for the education to occur at the junior high/middle school and subvarsity levels as at the varsity level. Just as we would not discriminate against one race or gender, we should not disadvantage one age or ability level. In fact, with a little less pressure to win, it is likely to see more education at subvarsity levels and more reason to sponsor them.
Second, I advocate the position that schools should avoid sponsorship of any activity for which a qualified head coach cannot be secured. Qualified personnel are, in order of priority:
-
a teacher within the building who has current CPR certification and completed CAP.
-
a teacher within the district who has current CPR certification and completed CAP.
-
a teacher in another district who has current CPR certification and completed CAP.
-
a certified teacher from the community who has current CPR certification and completed CAP.
-
a non-certified person who has current CPR certification and completed CAP.
I urge schools not to descend lower than this for program leadership. Coaches are the delivery system of the education in educational athletics; they are the critical link in the educational process. More problems occur than are worth the effort if the program is in the hands of an unqualified coach.
Next, I urge that schools rank sports on the basis of cost per participant, and give higher priority to sports that spread funds over the greatest number of participants.
Next, I urge that schools place lowest in priority the sports that cannot be operated on school facilities and create transportation, supervision and liability issues, and give higher priority to those conducted at or very near the school.
Next, I urge that schools place lowest in priority the sports which are most readily available in the community, without school involvement. If resources are precious, then duplicating school programs should be a low priority; doing what the community can’t do or doesn’t do should be given a much higher priority.
While I’m a fan of school sports, I recognize that an athletic program has as much potential to do harm as to do good. Programs without qualified coaches that are conducted for small numbers of students at remote venues and without comprehensive school oversight and support may create more problems for schools than the good they do for students.
Bare bones budgeting will require brutally honest assessments based on priorities like these.
