yeah, injuries can happen anywhere, and they will happen, that's just a fact of football...but to have them in a pre season game that means absolutely nothing to the starters, just seems to be a waste.
the pre season games are there for one reason, at least on reason from a football standpoint, is to find out who can play and who can't from the new guys...the 2nd and 3rd games the starters may use those as warm ups to get timing down and test some things, but all in all, they are not very valuable to the starters, only detrimental if they get hurt....
