The answer is no!  College players are always competing for the coach’s eye.  It is very hard to slow down or take it easy because you have to stand out or you can get left standing on the sideline.  Fights happen at practice because there are a great number of inflated ego’s on the field at the same time.  Add the pressure of trying to look good and leave and impression and it has all the ingredients of a good old brew-haha.  Coach, fights happen.  Yeah you don’t like to see guys fighting, but I love to see the aggression and toughness shown by the team.  Throw a few punches, push around for a bit and then forget the ego and don’t get flattened the next time you run over the middle.
