He made "freshman mistakes", clearly. He is an amazing talent, and I it might sound like my comments as an attack on Tua (they're not, he should be the starter from here on out), but I watched him get pulled from the CSU game because of issues. I watched him need to come out after Alabama wasted clock at the end of the Georgia game. I saw some of the things you expect from a true freshman. This has absolutely nothing to do with Tua, and everything to do with what you expect from a true freshman. Clearly he was better than like 99% of the true freshman QBs out there, it's not about that. Inexperienced players make mistakes, it's what they do.
The problem was Alabama didn't start with a soft part. Going back to A-Day, which I did in my first post in this topic, we saw that Hurts clearly managed an elite defense better than Tua. No knock on Tua, that's an experience issue. But to assume the Tua we saw against Georgia would have been the Tua we saw against FSU? That's a stretch, because the Tua that faced FSU would have looked a lot more like the one that faced CSU. I do agree that a nice soft patch of games would have cleaned up most that stuff though, I just have trouble finding the spot to do that, as mop-up duty by itself wasn't enough. Do you start him after the FSU game? That's the best window I see for that to occur, but I'm not sure any coach in the country would sit their starting QB after he just beat one of the top teams in the country.
My main point though is that while I'll concede that from the Auburn game on Tua might have been the better choice, it's really hard to find a "safe" spot to start him earlier. Hurts steered Alabama through rough waters, and Tua saved Alabama's season. Those two things co-exist just fine.
