This topic alway causes a little heated discussion.
It is clear that multi sport guys are usually good athletes. Most if not all of our sons are capable of playing several sports. Maybe not at the highest level.
The way I saw it was my son accepted the risk of playing Varsity BKTB and it was at the highest level and included trips all over the US. Thay had an annual trip to Vegas and Arizona where his coach now coaches. It didn't intefer with BB. If it did that would have prompted me to step in and try to stop him. He owes his dedication to BB which as I said was his ticket. We were only concerned about his last year of HS and up to then he could knock himself out. He was ready to just play the 2 sports and the only cocern was not getting injured. Sprained ankels, broken fingers can be deadly to a pitcher.It was his decision knowing the risks.
The question does it matter to a cocch if you played other sports I would agree with TPM and say NO. As I have said it is like play money. It doesn't buy anything. As far as questionaires asking about other sports they also ask about hobbies and other irrelevant stuff in regards to BB. All the coach cares about is your BB talent and ability to be a team player.
