When I was the Director of Coaching for a Florida soccer club a player arrived late for practice and I asked him why he was late? He replied that he had just finished cross country practice. While I walked around observing the different practices I noticed he was leaving practice before the other players and I asked him why he was leaving practice early? He told me he was playing club lacrosse and had to attend lacrosse practice! I am not sure if he ever became a great lacrosse player or a great cross country runner but he, certainly, never became a top level soccer player.
