I went back and watched a lot of Jameis Winstons games, and needless to say he had a heck of a year in 2013, but I believe he will have a set back year in 2014 and heres why:
For starters, there wasn't a more dominant receiver in college football this past season than Kelvin Benjiman. Benjiman was simply too good for college with his Calvin Johnson esqe ability. There was no corner in college who could cover him one on one which caused defenses to roll coverage to his side more often than not, which also caused Rashaad Greene or Kenny Shaw to have one on one coverages. But when Benjiman did have one on one coverage, Winston could simply lob it up to him at any point on the field and it was, of course high percentage that Benjiman would come down with it. You just can't gameplan for Benjiman, especially when he wasn't the only weapon.
Secondly, Kenny Shaw was thee best slot receiver in the ACC. His route running/catching ability is elite and when Winston went through his progressions and couldn't find Benjiman or Greene, it was high percentage that Shaw was open as he has a knack for finding open windows to sit in. Kenny Shaw to me, will have a long productive career in the NFL. I can just imagine the Patriots drafting him to be Tom Brady's new go-to-guy.
I'll conclude that, yes they bring back Rashaad Greene and he is pretty good, but after Greene there aren't any proven receivers. There is no Benjiman who you can simply just "lob it up" to, and there is no Kenny "I keep them chains moving" Shaw. Winston will have to think and go through his progressions way more and longer than he did last season. No question that Winston has the goods, but as a result of not having Benjiman and Shaw, I will bet that he will face the adversity that should have faced as a freshman. I think he will throw more picks, get hit a lot more, look more confused and not look so "unphaseable" if you will. Like I said, he undoubtedly has got the goods, but he will go through the rigors in 2014
And oh, they better hope Karlos Williams can be "the guy" and not just the guy who racked up all those yards in mop up duty, because there isn't any proven backs either with the departure of Freeman and Wilder.
