Mater Dei Named “Most Improved Team of the Year” named Mater Dei boys varsity lacrosse as the “Most Improved Team of the Year,” following the Monarch’s rebound from a 3-12 season in 2013 to an 11-7 campaign and a playoff berth under first-year coach Paddy Chester in 2014. caught up with Coach Chester to find out how he and his staff were able to make such a profound impact so quickly:

Mater Dei (red)
Mater Dei (red) Mater Dei is a proud sports institution. How did you get your boys to buy into your system so quickly?

Paddy Chester: Mater Dei has a long and strong history of sporting prowess among numerous sports. I arrived at Mater Dei with that in the front of my mind. Lacrosse needed to be a part of that history and success. As this as one of my long-term goals, I was able to present to the players where we were going and what is what going to take hard work , commitment. But the rewards were to be a part of writing the prologue to the Mater Dei lacrosse story . Who wouldn’t want to be a part of that? This is a great school both academically and athletically, so we have to be and will be part of that success and growth .
I kept things simple but was honest with them all — my expectations and goals along with what it will take. This is just the start of a major rebuild and I am pleased as to where we are right now. Still a way to go though!

MLOC: What is your coaching philosophy?

Mater Dei

Coach Chester: Hard work, hard work and hard work bring rewards, success and get things done. Lacrosse is really a simple game. Catch, throw, ground ball and run. These fundamentals are vital but need to be done correctly. By focusing on this things can happen and the game can be played. Give everything you have and you will see what you get back. And, of course, have fun playing the greatest game there is.
We have driven our program on three levels: Pride, Passion, Belief. Pride in our school, the game of lacrosse and each other. Passion in the game and play always with that in mind. Play as lacrosse is what is running through your veins and if it is your last game. Just leave it out there on the field, all of it. Belief in your teammates and coaches and of course your talents and that anything can be possible.
MLOC: Was there a single game this year where you and the boys realized this year was going to be different?

Coach Chester: I think that our first home game was a major game for us. A close game against a well-organized, talented El Toro squad. We had to fight and managed a win in OT. This brought the team together and made a huge impact in this program. We had a great start to the season using this game as a changer.

MLOC: You rebuilt your coaching staff from scratch. Tell us about them and your backgrounds.

DSC02392Coach Chester: I was incredibly fortunate to have two very good and experienced coaches working with me. Ray Ralph came on board with me this year to join Ryan Kelaher who was starting his second year with the program me. Having Ryan here helped tremendously with the fact that the boys had someone they knew and trusted. Coach Ralph is a legend who coached at Foothill from 2007-2012 with Coach Jon Fox. (see below for more on all three coaches).

MLOC: Who were the key leaders on this team that led the turnaround?

Coach Chester: We had a number of key players, but for me the whole team were important from buy-in to commitment to trust the coaching staff and work hard to achieve what we need to get done. Offensive play was driven by Nick Southron with the midfield work horse of Caden Bevilacqua being a big part. Defensively I had a very tight and talented unit driven by Nick Bauer at the back and Bennett Brewer at LSM plus solid continuous play from Jake Stanford.
I cannot praise the boys enough for reaching the goals set up they should be very proud of what they accomplished and the standard that has now been set for Mater Dei Lacrosse.
