And it is a legitimate excuse too.
If UT isn't suffering more injuries on a routine basis then possibly. But it at least appears that UT IS suffering a higher rate of injuries than other programs. It may not be a huge margin... but it doesn't have to be a huge margin. One or two good players can often be the difference in 3 or 4 wins.
At some point, a coach becomes responsible for injuries too if a) many come outside of games and b) the come at a consistently higher rate. That appears to be the case right now.
It IS a fixable problem. Other programs do not have the same level of injuries and manage to field good, physical teams. I have confidence that Jones can do so as well.... but he DOES need to.
