“As a coach, especially working with young adults, my main goal is to instill a proper work ethic and mentality. At this point in the game, these players are aware of their talents and skill set, but the next step is mental toughness and bringing the proper mentality everyday. In order to do this, communication needs to be on a level that the players can comprehend, and I believe that I am a coach that can understand this age group of players and relate to them in many ways. Something I wish to get out of this summer is to have my love and passion for the game reach out to my players to show them not to take this game for granted, and cherish every moment we have to play for as long as we can.”
