How can you NOT blame Nick Saban for Tuas injury?

It was 35-7 at the time the injury occured.
Miss. State had about 1% chance of coming back to win.
Tua was already hurting with his leg injury.
Nick needs to take some responsibility. He did the same thing to QB Matt Mauck in 2002 when coaching LSU in the LSU vs. Florida game. LSU was up 36-7 late in the game and he left him in and he got hurt. It makes no sense. The little man needs to man up and admit his mistakes but it's apparent he don't want to do that. Fire away. Sad day for Tua and Alabama and it could have been avoided by putting him on the bench when the game was clearly out of reach for that mighty Miss. State team to come back. Shame on you Nickie.
