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.”

Working Through Transfer Trends
December 2, 2015
By Jack Roberts
MHSAA Executive Director
One of the responsibilities that schools have asked organizations like the MHSAA to execute is the management of transfer student eligibility. Historically, many associations have linked eligibility to residence ... thus, for some the regulation has been called the “Residency Rule” or “Transfer/Residency Rule,” not merely the “Transfer Rule.”
Over the years, as society became more mobile and families less stable, these rules became more and more complicated; and now, for most state high school associations, this is the regulation that consumes the most (or second) most pages of their handbooks. Over the years, this has also been the regulation most frequently challenged in court.
Over the years, some states have relaxed their transfer rule and others have refined their transfer rule. In either case, the transfer rule remains an imperfect rule, an imperfect net. Sometimes this net snags students who should not be made ineligible, and for those situations all associations have arranged some kind of waiver or appeal process.
And sometimes, and much less easily solved, the net fails to catch the situations it really should ... the transfers that are not hardship related or the result of some very compelling educational need, but those that are obviously for athletic reasons. It is those that we have been most focused on in Michigan.
Our first effort to get at the most problematic transfers was the adoption for the 1997-98 school year of what we called the “Athletic-MOTIVATED Transfer Rule” ... Regulation I, Section 9(E). Examples of an athletic-motivated transfer are included in the rule. The rule only applies to transfer students who do NOT meet any of the stated exceptions for immediate eligibility and are ineligible for one semester under our basic transfer rule. They become ineligible for 180 scheduled school days if there is a finding that the transfer was more for athletics than any other compelling reason.
This effort has not been successful enough because it requires a school that loses a student to another school to promptly allege to the MHSAA office, with supporting documentation, that the transfer was more for athletic reasons than any other compelling reason. The receiving school then must respond to those allegations. Then the executive director makes the decision. The unfortunate result of applying this rule is that it usually causes hard feelings between the schools, and hard feelings toward the executive director by the school decided against. In 17 years, schools have invoked this rule only 45 times.
Our more recent effort to address the most egregious athletic transfers resulted from requests from the coaches associations for wrestling and basketball, which were watching too many students change schools for athletic reasons, usually related to an out-of-season coaching relationship. The new rule – the “Athletic-RELATED Transfer Rule” – is Regulation I, Section 9(F). The difference between Section 9(E) and the newer Section 9(F) is that in 9(F) one school does not have to make and document allegations before staff can act. If MHSAA staff discover or are informed of any of the circumstances listed in 9(F), we can act. Again, the rule only applies to those transfer students whose circumstances do NOT meet one of the automatic exceptions. It applies only to students who are ineligible for a semester under the basic transfer rule. If there is a finding that one of the athletic related “links” exists (usually an out-of-season coaching relationship), then this transfer student who would be ineligible for one semester is made ineligible for 180 scheduled school days.
So far, it appears that 9(F) may be a better deterrent than 9(E). It has been referenced when students are rumored to be transferring, and it has stopped many of those transfers before they occur. We expect 9(F) to be an even better deterrent in 2015-16 because the rule has been broadened to apply to administrators and parents (not just coaches) and to address directing and coordinating athletic activities (not just coaching).
We have said that if this latest effort does not succeed in slowing athletic transfers, then the next step is 180 days of ineligibility – at least in any sport the student played in high school previously – for all transfer students who do not qualify for an exception that permits immediate play. I fear that would catch far too many students who should not be withheld so long from competition and could lead to a period like the early 1980s when the MHSAA, at the request of the state principals association, adopted the core of the transfer rule we have today and which resulted in a period of busiest litigation for the MHSAA when, at one time, the association had more than a dozen cases in court simultaneously on transfer matters. We’ve got to make the current rules work – with tweaks, perhaps; but not with radical revision.
