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.”

Catch These New Rules as Fall Kicks Off

August 7, 2014

Second Half editor

The first practices of 2014-15 begin next week for approximately 110,000 student-athletes taking part in eight sports in which the Michigan High School Athletic Association sponsors postseason tournaments, with nearly 41,000 football players practicing under a new policy in that sport aimed at continuing to improve player safety.  

The new practice policy was proposed by a Football Task Force made up of coaches, administrators and MHSAA staff which met during 2012 and 2013, and approved by the MHSAA’s Representative Council at its Winter Meeting on March 21.

The modifications are meant to promote heat acclimatization and limit helmet-to-helmet contact during practices. They include:

  • During the first week of practice, only helmets are allowed the first two days, only shoulder pads may be added on the third and fourth days, and full pads may not be worn until the fifth day of team practice.


  • Before the first regular-season game, schools may not schedule more than one “collision” practice in a day. A collision practice is defined as one in which there is live, game-speed, player-versus-player contact in pads involving any number of players.


  • After the first regular-season game, teams may conduct no more than two collision practice days in any week, Monday through Sunday.


  • No single football practice may exceed three hours, and the total practice time for days with multiple practice sessions may not exceed five hours. Neither strength/weight training activities nor video/classroom sessions are considered practice for the purposes of the three or five-hour limits.


Previously, schools were required to conduct at least three days of practice without pads before beginning contact. The change to four days for gradual addition of pads was added to assist athletes in acclimating to being physically active in hot weather. Guidelines reducing the amount of collision practice go hand in hand with rules changes that have been made to reduce helmet-to-helmet contact in game situations. The policies in detail can be found on the Football page of the MHSAA Website.

“We think these new policies, with respect to the number of collision practices there can be before the first game, and after the first game, really are where 85 to 90 percent of our coaches already were,” said John E. “Jack” Roberts, executive director of the MHSAA. “This new policy sends a signal to that 10 to 15 percent to get on board with the rest of us to make football just as safe as it can possibly be.”

Practice in football must begin on August 11 for all schools wishing to begin regular-season games the weekend of August 28-30. Schools must have 12 days of preseason practice at all levels before their first game, and those 12 days of practice may not occur before 16 calendar days.

Practice sessions for all other sports begin on Wednesday (August 13).  In golf and tennis, competition may commence no earlier than after three separate days of team practice, and not before seven calendar days. The first day competition may take place in golf and tennis is August 20. In all other fall sports, contests can take place after seven days of practice for the team and not before nine calendar days. The first day competition may take place in cross country, tennis, soccer, swimming and diving, and volleyball is August 22.

Only one football date precedes Labor Day, and most varsity games will take place on Thursday, August 28, that week. Subvarsity competition may begin on Wednesday, August 27. In Week 1, 255 games will be played on Thursday, 53 contests will be played on Friday, and five games will be played on Saturday. 

Continuing the focus on player safety, a number of rules changes were made in football for 2014:

  • Rules were added restricting targeting of opponent and illegal helmet contact with defenseless players, with both resulting in 15-yard penalties. Targeting is defined as taking aim at an opponent with the helmet, forearm, hand, fist, elbow or shoulder to initiate contact above the shoulders and with an intent beyond making a legal tackle or block, or playing the ball. A defenseless player can be considered one no longer involved in a play, a runner whose progress has been stopped, a player focused on receiving a kick or a receiver who has given up on an errant pass, or a player already on the ground.


  • Illegal contact to a quarterback now will be considered roughing the passer, and the offense will receive an automatic first down in addition to the previous 15 yards from the penalty.


  • On kickoffs, the kicking team must have at least four players on either side of the kicker, and no kicking team players except for the kicker may line up more than five yards behind the free-kick line. These changes were made to improve safety by balancing the kicking formation and shortening the potential run-up by kicking team players heading down the field to tackle the ball carrier.


A number of significant rules changes will go into effect for other fall sports:

  • In cross country, the ban on wearing jewelry has been lifted (and also for track and field in the spring). The National Federation of State High School Associations deemed the ban unnecessary in these two sports because there is little risk of injury with minimal contact between competitors. Elimination of the rule will allow officials to further focus on the competition.


  • In soccer, Michigan has adopted the National Federation rule stating home teams must wear solid white jerseys and socks, with visiting teams in dark jerseys and socks (dark defined as any color contrasting white). Also, officials may now wear green and blue shirts in addition to red and black as alternates to the primary yellow shirt with black pinstripes.


  • Also for soccer, both field players and goalkeepers must now leave the field when injured and the referee has stopped the clock. Previously, an injured goalkeeper was not required to leave the game when the referee stopped the clock; going forward, the keeper must be replaced.


  • In swimming and diving, one change affects the beginning of races and another impacts a specific event. The use of starter’s pistols is now prohibited; starters must use an alternative sounding device to start races. Additionally, in the backstroke, a swimmer may not submerge his or her entire body after the start except for during turns. The swimmer must remain on or above the water surface on the finish, eliminating the abuse of submerging well before touching the wall. This change also applies to the finish of the backstroke leg of the individual medley.

The MHSAA is a private, not-for-profit corporation of voluntary membership by more than 1,500 public and private senior high schools and junior high/middle schools which exists to develop common rules for athletic eligibility and competition. No government funds or tax dollars support the MHSAA, which was the first such association nationally to not accept membership dues or tournament entry fees from schools. Member schools which enforce these rules are permitted to participate in MHSAA tournaments, which attract more than 1.4 million spectators each year.
