It's easy to second guess things now, but for most of the half I think Alabama did a decent job of handling Tua. Balanced attack, and then when it seemed like an obvious situation to take him out, it all fell apart. Now the only question is just if that's the end of his Alabama career and what this means for his future.
I think a lot of people will put this all on Saban, and ultimately the responsibility falls on him. When making that choice, Tua's characteristics had to come into play. If Tua doesn't try to extend that play and just throws it away, he is fine. He didn't though, and we all saw what happened. Alabama just can't let another situation like this happen, no matter how good the QB is. You do what you have to do to protect your quarterback, even from himself...
