With the weapons he will have at his disposal at wideout (Cooper, Norwood, Christion Jones, Bell, White, Black, Cyrus Jones), Running Back (Yeldon, Fowler, Hart, Drake, Tenpenny, Henry), and someone as athletic/versatile as O.J. Howard, I expect another phenomenal season. Adding a guy like Robert Foster would just be an extra layer of icing on the cake.
As far as the O-Line is concerned, we will lose 3 starters but I've been impressed with some of the 2nd teamers that have gotten quite a bit of playing time, namely, Arie Kouandjio and Kellen Williams. They will only improve with another offseason in the weightroom with Cochran, and going up against a Defensive Front every day in practice that should have a lot of talent and depth. I like the Offensive Lineman we have in our recruiting class already, and if we can add Tunsil and another lineman, it would be another case of "the rich getting richer."
