Honestly, Eason didn't overly impress last year....and looked downright bad at times. However, the kid was a true freshman playing under a 1st year coach. It should be expected to assume he'll show natural progression and improve as he matures (from year to year). So, I'm going to assume he plays better this year. How much better, who knows? But, better than last year. He does need his supporting cast to perform however, and if his OL is porous and his WR's keep dropping passes, etc he could have a not so good year. But again, who knows? He could be a future Heisman winner, or lose his job to another QB. I think it's way too early to assume Smart is another Muschamp. He is one of (if not THE) longest tenured Saban assistant, unlike Muschamp who had been away from Saban for 4 or so years before taking the UF job.
I think Tennessee is going to be okay at QB. Their defense fell apart last year. So they could easily be an 8-4 type team again. Jones hasn't shown much more than to be a middle of the road coach, 7 to 9 wins. He's recruited solidly, so he could have a breakout year one of these years....but doubtful.
