The suggestion is not that a lacrosse only kid would be rejected versus a multi-sport kid.

The suggestion is that playing more than one sport when you are a laxer is a proven good thing.

If your HS coach is advising you that lacrosse only is the best way to go, I would beware of that coach.

Jim Brown would have been great at either sport if he played only one. Jim Brown was greater at both because he played both.
