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.”

Sorting It Out

February 4, 2014

The MHSAA has a good relationship with the high school coaches associations of Michigan in spite of the fact that the MHSAA sometimes befuddles and frustrates some associations’ leaders and members. This occurs, for example, when a coaches association’s board of directors votes unanimously in support of a change in policy or procedure which fails to be adopted by the MHSAA Representative Council. Every so often over the past 25 years, I’ve had to provide reminders of why this occurs – in fact, why it must occur.

First, a coaches association is just that – an association of coaches; and coaches are but one of the many important voices to whom the MHSAA pays regular attention. The MHSAA also must hear the opinions of athletic directors, principals, superintendents, boards of education, contest officials and others. Typically, coaches desire more of everything: contests, classifications, trophies and medals. Just as predictably, most administrators seek reasonable limits on such things and can often be heard to say, “Enough is enough.”

Second, the makeup of many of our state’s high school coaches associations’ boards of directors, and even the associations’ members, do not reflect the MHSAA’s full membership. Understandably, many coaches associations’ board members are disproportionately from large schools in the southern or even southeastern part of Michigan.

And third, by their nature, coaches associations advance proposals for a single sport, which could impact other sports positively or negatively. There is no question that if one sport “gets” something, like another tournament classification or division, other sports will seek the same consideration which may or may not be practical for or beneficial to other sports.

When considering a proposal from a coaches association, MHSAA Representative Council members will almost always ask themselves: “Who’s not in the room? Who are we not hearing from? Is there another side of the issue? How does this play out among small schools, or urban schools, or northern schools? How will this affect other sports?”

We look to coaches associations for sport-specific advice; and we urge them to seek input from a constituency that is as large and diverse as possible. We look to other stakeholders to add their advice and counsel to the process; and we depend on the Representative Council to sort it out and seek the proper balance.
