RB:
* Andre Ellington. The more Sir Juke was getting banged up the more the Cardinals' offense started to sputter. Losing Jonathan Dwyer and the touches he was supposed to get per game was tough on Ellington. It seems reasonable to assume moving forward that Ellington cannot be a work horse RB---and if the Cardinals add a work house RB this off-season, it would allow BA to use The Juke in the diversified role he thrived in as a rookie. BA claims that Ellington is as good a receiver and route runner as any player on the team. Working Ellington more out of the slot could be a real boon for the Cardinals' productivity. But there's no question about it: as Sir Juke goes, so goes the Cardinals' offense.
* Stepfan Taylor. BA's reluctance to increase Taylor's role in the offense, particularly after Dwyer was cut is telling in the sense that BA would prefer a more dynamic RB. Taylor is a blue collar RB who plays hard and steadily. He's a good blocker and he doesn't fumble. He improved his speed and agility this year, but is still slower than the coaches prefer. However, Taylor is solid on STs and is an all-around, steady player. Nonetheless, Taylor may have to beat out Robert Hughes for the #4 RB slot next year, assuming a work horse RB is added.
* Robert Hughes. Was raved about in camp by BA for his versatility, his blocking and his uncanny pass receiving skills, and yet has been vastly under-utilized in the offense. When Hughes has been called upon he has delivered in spades. The questions are: why doesn't BA throw to him more and why isn't Hughes used as the power RB when the team needs to run between the tackles? Hughes is just as fast, if not faster than Taylor---and he's more rugged.
* Marion Grice. The Cardinals like his versatility, as evidenced by the times he is being used as a slot WR. There is real talent here. Could he become a lead RB? The fact that Taylor is getting the touches at RB right now would suggest not. However, if Grice has a Stevie Breaston like 2nd year burst, Grice might become quite a factor.
* Kerwynn Williams. What a diamond in the rough this kid appears to be. He gets after it---hits the whole hard, does not go down on first contact and has a nice burst in space. Gutsy, quick and gritty. While it would be unlikely for him to ever be the work horse RB, he could be the change of pace RB when BA wants to use Ellington more in the slot.
Many of the early mock drafts have the Cardinals taking a RB in the late portion of Round 1---the three names that pop up most are Todd Gurley, T.J. Yelton and Melvin Gordon.
If the Cardinals can take care of the defensive needs in FA---then one of those three RBs might make sense.
