Arian Foster gets my vote. From what I have heard, he is coming along strong with the help of Drayton. He isn't the fastest, but he can find the hole and make you pay. With this being Crompton's first year starting, Foster will be getting some more carries earlier in the season while Crompton is getting set with the offense. He is also going to be one of the leaders of this team.
I think Josh Briscoe will have a very good year also at WR.
