I agree with Theismancarr, that these injuries are freak injuries. I highly doubt that Loren Landow's program is detrimental to the players' health overall, since he has had success at all levels.
This team looks fast and athletic, and I don't see any dropoff at all going from Matt Balis to Loren Landow.
The defense looked very fresh against Army, despite Army having held the ball for 40 minutes of time, and the defense not getting much rest at all.
Also, the way they held up in that swampy weather in College Station shows how effective Landow's program really is. The TAMU guys were completely gassed by the middle of the 4th quarter.
