"Coaching is a profession of love. You can’t coach people unless you genuinely care for them. Because no one cares what you know until they know that you care! Without love for your players, it will be difficult to build a relationship with them. Without the relationship, it’s going to be tough to get them to work as a team, and to follow you and your instructions. A leader can get by with just respect or fear, but a coach is much more than just a leader of the players. To encourage and to mentor, these things take more than simple authority. My job is not to be easy on my players. My job is to take these great young people and to push them and make them even better!!! Be great today... Lead someone!!!"
