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.”

Three Michigan high school varsity coaches have been recognized among 23 National Coaches of the Year for 2020-21 by the National Federation of State High School Associations (NHFS) Coaches Association.
Ann Arbor Pioneer girls swimming & diving coach Stefanie Kerska, Bronson volleyball coach Jean LaClair and DeWitt football coach Rob Zimmerman were selected by a committee including representatives from all eight NFHS sections – Michigan is part of Section 4 with Illinois, Indiana, Iowa and Wisconsin.
The following brief bios includes an excerpt from each honoree’s coaching philosophy, which nominees were asked to submit after being identified as candidates for the awards.
Stefanie Kerska took over both the Ann Arbor Pioneer girls and boys swimming & diving programs during the 2014-15 school year, and she has led the girls to the last two Lower Peninsula Division 1 Finals championships; her 2020 team doubled up the runner-up’s score with 368 points, and this fall’s team climbed even higher with 405.5 points at the season-ending meet. She also led the girls team to a runner-up Finals finish in 2019 and the boys team to last season’s LPD1 Finals championship. Kerska previously served as an assistant coach at University of Michigan from 1997-2012 and on the USA Swimming national team staff from 2008-16. She remains active with USA Swimming, the FINA Swimming Development Team and as a presenter for the Summit for Empowering Women in Swim. She was named the Michigan Interscholastic Swim Coaches Association Coach of the Year for both Division 1 girls and boys during the 2020-21 school year.
“Athletics starts with a belief in belonging and making every team member feel safe and valued. Teammates should depend on coaches and each other for support, guidance and motivation to be the best they can be. Athletics should create an environment where effort, attitude and dependability are valued and required for success. It is often said that athletics builds character. I, however, believe it reveals it.”
Jean LaClair ranks fourth in Michigan high school volleyball coaching history for varsity victories with a record of 1,289-398-99 having led Midland Dow from 1988-90, Pinconning from 1997-99 and Bronson beginning with the 2000-01 winter season. She’s coached Bronson to five MHSAA Finals championships – including four straight in Class C/Division 3 from 2015-18 – and her last two teams have reached the Division 3 Quarterfinals and Regional Semifinals, respectively. She is a longtime executive board member of the Michigan Interscholastic Volleyball Coaches Association and has served as president, and was a 2017 inductee to the Michigan High School Coaches Association’s Hall of Fame. She also serves as Bronson’s athletic director and has received both the MHSAA’s Women In Sports Leadership Award and Allen W. Bush Award.
“High school athletics should be a lifelong, fun experience for our student-athletes where they learn what it takes to be a part of a team, what it means to work hard for the team. Those who play competitive spots in high school demonstrate more confidence, leadership and self-respect. They learn to set goals and manage their time! They have a better appreciation for diversity and a more developed sense of morality. These are all reasons why athletics are important, and I love working with our kids to make them better leaders for the community and world.”
Rob Zimmerman led DeWitt to the last two Division 3 championship games and the Panthers’ first MHSAA Finals title to cap the 2020 season with a 12-0 record. He’s built a 241-67 record coaching DeWitt’s varsity since 1999 after previously coaching the varsity at Cedar Springs from 1996-98. He also has served as a head varsity track & field coach and middle school wrestling coach during his tenure in school sports, and he has served as both a regional director and on the executive board for the Michigan High School Football Coaches Association. His teams total have played in six MHSAA Finals, to go with 19 league, 14 District and 12 Regional titles during his 23 seasons at DeWitt. He has five times received statewide Coach of the Year recognition from The Associated Press, and in 2020 was named the state Dream Team Coach of the Year by both the Detroit Free Press and MHSFCA and state Coach of the Year by the MHSCA and Detroit Lions.
“In an ever-changing world that poses more social and emotional challenges for young people than ever before, systems that can provide a foundational support and teach high levels of collaboration, discipline, accountability and relationships are more important that ever. Athletics provides young people the opportunity to foster and cultivate these key traits that are crucial for their development. For future success, students need to be equipped to handle a variety of diverse situations and work with a variety of diverse people. This is sports at its core.”
Rockford wrestling coach Brian Richardson was honored in Section 4 after leading the Rams to the Division 1 Semifinals and a 20-4 record.
The NFHS has been recognizing coaches through an awards program since 1982.
