Not only is that true for the game but it is true in RL!!! This isnt a negative thing at all to me. I dont know what football games you watch but people go down a lot. Not every injury is a series one, just like in the game players go down with a bruised rib after a hard run up the middle and take the next 2 plays off. I dont see your argument at all sry. Show me a team that isnt dealing with injuries game after game.
Just off the top of my head you have Tenn missing a WR for the year and the season hasnt started. UCLA has had a horrible time keeping QBs healthy. I think the big thing is that NCAA guys are fans of there favorite player more then the team sometimes and when you only get 4 years or less you want your guy to go all out every game for as long as you have him and a long term injury ruins that.
