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.”

Teaching ABC's of Pressure Situations

October 30, 2013

Coaches have seen the signs: Athletes having too much or not enough energy prior to a game, quickening breathing, sweating more than usual, being unable to focus on important details, and having their minds wander from the present to “what if” scenarios and past mistakes. 

Athletes deal with pressure in many ways. Although some handle it well, many do not have the tools to perform to their full abilities in these situations. Most athletes place a high importance on succeeding in sport, and when athletes reach regional, district, or state championships, the pressure they feel may become overwhelming.

How athletes handle this increased pressure can often mean the difference between winning and losing. Therefore, helping athletes deal with it is something coaches should consider prior to athletes encountering these high-stakes situations.

Unfortunately, there is no magic elixir for helping your athletes work under pressure. But if these ABC’s of pressure situations are followed, your athletes will be much better equipped to cope, and the chances of their performance levels dropping significantly will be reduced. 

1. Act the Part         

How you as coaches act influences your athletes. For better or worse, athletes notice your emotions in response to these situations and take cues from how you handle pressure.

You are a demand on your players’ attention – you can add or reduce your players’ perceived stress by how you act. Understanding the demand you place on players requires self-awareness. How do you respond when a key call goes against you? Do you have nervous habits that athletes may notice? What messages are you providing to your athletes – both verbally and non-verbally? Athletes pick up on these non-verbal cues, so you must be aware of how you respond to these situations.

It is important to remember emotions are not always negative – rather acting differently than normal can be a signal to your athletes that you are stressed. Strive to be consistent in your actions – whether you are coaching during a preseason match or championship contest. These situations are stressful for you too, but you need to be the constant your athletes look to for stability. 

2. Breathing – Remember to do it

It seems like a simple thing, but when athletes’ emotions are running high, they forget how to breathe – or, at least, forget how to breathe properly. Worse, they often think they are breathing normally but don’t notice breaths are becoming shorter and shallower. Teaching athletes to breathe properly when not in pressure situations will help them have the tools to rely on when they encounter more intense scenarios. 

For proper breathing, athletes need to do so from the belly and not the chest. The pace of this breathing should be 6-2-7; that is, have athletes take a deep breath from the abdomen for six seconds, hold for two seconds, and then finally slowly exhale completely for seven seconds. This breathing strategy is ideal for pregame situations to quiet nerves and help athletes get ready to play, but a condensed version (3-2-3) can also be used for quick breaks in the action like a timeout or court change.

3. Control the controllables

During times of high pressure, athletes sometimes feel they do not have control over their own performances. It is important to help athletes focus on things they can control and not worry about those that cannot be changed or are outside their influence. 

Instead of athletes dwelling on aspects that are out of their control like unusual game times for championship finals or a referee’s bad call, help them focus on completing their warm-up preparations and how they can respond to poor calls. Helping focus athletes’ attention on things they can control will help them better handle pressure situations and leave them feeling less helpless

Athletes’ emotions are typically out of their control, but how they view them and respond to these emotions are under their control. Author and preacher Charles R. Swindoll said, “Life is 10 percent what happens to you and 90 percent how you react to it!” Be sure your athletes know how to respond when difficult situations arise. 

Conclusion: Fearlessness is an assembly

Not all athletes react to pressure situations in the same manner, but all athletes can benefit from these simple suggestions. Remember to ACT THE PART of how you want your athletes to act, teach your athletes proper BREATHING techniques, and help athletes focus on CONTROLLING THE CONTROLLABLES

Good preparation is the key to performance. Increase self-monitoring and give athletes the tools to succeed in pressure situations; they, in turn, can be in a better position to succeed. However, like any skills, they must be practiced accordingly, and one session will not solve all issues. Devote the time to train athletes in these skills, and when the need arises they will have them ready to use. 

Good luck this season!
