re: Has a player ever won the Camp, Walker, Maxwell, and Heisman all in one year?

Henry hasn't peaked. I've said that before on here many times. He lacks lateral movement as you said, but he has nothing to gain by coming back for another season other than working on that particular part of his game along with getting more receptions.

That being said, he will learn in the NFL. He already has enough raw skill to be the best RB in CFB, his blocking ability, speed and strength, are good enough that he can work on his lateral movement and juke moves on Sundays next season.

ETA: And for the record, as I have also posted many times, other than Kelly at Center, this OL is average at best with Nysewander being the second best blocker on the team not counting WRs blocking downfield which has been a staple of Bama WRs since Saban arrived and brought in Julio Jones. OJ Howard has done good blocking too since he hasn't caught a TD pass all season and was so surprised to have a pass thrown his way in the SECCG last week that it hit him in the hands and he was so shocked he dropped it.
