I am not saying they have the best starting running back (but Bell won't be too far off of being that this year, in my opinion), but looking at the unit as a whole, I am not sure they don't have the deepest, best, overall RB unit in the NFL.
Watching Bell down the stretch, he flashed all the skills that the team saw when they drafted him: power, quickness, balance, vision. And he has elite hands for a running back.
Blount is a beast for a #2. How many #2's are as good as he is? Not many. Almost no one. He has serious power and fire in the belly.
And now that we have battered teams with Bell and Blount we melt their faces off with Dri and his insane speed, vision and balance. (BTW, I chose the video bases on which one had the best music. "Pop Dat Thang" is such a killer jam. How can you not dig that? The jam after it is dope too.)
What team possibly has a better RB unit than we do? Maybe Philly.
