Jenny Finch would not be "Jenny Finch" if she did not commit to softball. There are few athletes who become elite in one sport playing several. I know there are exceptions but not many and exceptions can be made. But, I find it hard to believe that 1/2 the team are gifted athletes.
Sorry, but I just don't agree with that statement. For example, if you go back and look at how many pro athletes were multi sport athletes in high school, it's mind boggling. John Elway, Dan Marino, etc., etc. The list goes on and on and includes most of the NFL and MLB Hall of Famers. Kids specializing in one sport is a fairly recent thing. I realize that it gets frustrating when kids miss softball practice for other sports, but you have to realize that those "other sports" are excellent cross training for a softball player. The results can be quicker reflexes, faster running speed, better hand eye coordination, more explosiveness, etc.
This is why D1 coaches love multi sport athletes.
