The thing you'll also notice is that if you have a player who is injured a lot, he's also fouled out a lot. Those things go hand in hand; all injuries in BB are caused by fouls, and highly aggressive players foul a lot and draw more fouls. It's a cascading effect where you may end up with, for example, a player who gets injured four times in a season and fouls out another four times in that same season before you stick him on the TL to get him the heck away from your roster, not that I'm bitter or anything.
