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.”

Country Day Two-Time Champ Moore Building Perennial Winner at Harvard

Carrie Moore says her high school sports experience in Michigan has “left a lifetime impression on me.”
Back in the early 2000s, Moore certainly had a fulfilling one while starring as a two-sport standout at Detroit Country Day.
In basketball, she was a four-year varsity performer for legendary head coach Frank Orlando, helping guide Country Day to Class B titles in 1999 as a freshman and 2002 as a senior. During the latter, she was a first-team all-state performer and scored a team-high 18 points in a Semifinal win over Flint Powers Catholic.
Moore also was a standout soccer player on that Country Day varsity powerhouse for three years.
“Who I am as a leader, as a competitor, and a team player is because of what I learned about the process in high school as a student-athlete,” Moore said. “The pursuit of excellence isn’t always easy, but I learned at such a young age that I can do hard things. I was challenged because I was surrounded by the best on the court and in the classroom, but ultimately it brought out the best version of myself and I was so prepared for what came next after graduation.”
Make no mistake about it, Moore has continued to do great things since graduating from Country Day in 2003.
She is currently the head women’s basketball coach at Harvard, where she just completed her fourth season and has amassed an 80-41 record with the Crimson. This past season, she helped guide her team to a 20-12 record and the Women’s Basketball Invitational Tournament.
Moore was a terrific college player at Western Michigan, finishing as the school’s all-time scoring leader with 2,216 points and earning Mid-American Conference Player of the Year in 2007 after averaging 25.4 points per game. But she initially wasn’t planning on being a coach once her time at Western was over.
After playing one season professionally in Poland and then being cut twice by WNBA teams during training camp, Moore had an opportunity to join the coaching staff at Princeton in 2010.
From there, the coaching bug bit her, so to speak.
“Being a part of that program allowed me to see the lasting impact I could have on young women in growing them as people and players, and ultimately, give back to the game that gave me so much,” Moore said.
Moore was on the staff for two seasons at Princeton, and then moved on to Creighton, where she spent five years as an assistant coach.
Following a second stint as an assistant coach at Princeton that lasted four years, Moore moved on to North Carolina, where she spent two years as an assistant coach and recruiting coordinator for the program.
A native of Lathrup Village, Moore then briefly returned to her home state for the 2021-22 season, serving as an assistant coach and recruiting coordinator for University of Michigan’s team that went 25-7.
After that season, the opportunity at Harvard came about, and Moore has proved she can be successful running a program as well.
In her first season, Moore set a program record for most wins by a first-year head coach (20). Two years later, she guided the Crimson to its first Ivy League Tournament title and back to the NCAA Tournament for the first time in 18 years.
Even to this day, Moore is influenced by her time at Country Day and in Michigan. She speaks regularly to Orlando, picking his brain for advice or an answer to any other question that might come up.
“I keep in touch with Coach O as often as I can,” Moore said. “He reaches out after big wins or tough losses and always reassures his belief in me as a leader of young women. His mantra ‘Believe It’ is living on within our program at Harvard, and I hope he feels deeply connected to it because of it. I will always honor him in any way that I can, as he has shaped me greatly as a human and coach.”
Moore hasn’t had a player from her home state on her Harvard roster. But she said Michigan is an important recruiting area, and she’s keeping an eye out for prospects.
“I’m very hopeful that it will happen one day,” Moore said.
