The Steelers OC Todd Haley called LeVeon Bell a "three-down back, which is a big thing for us."
Haley said running backs coach Kirby Wilson looked at tape of some of Michigan State's roughest games -- "The games where the back isn't necessarily getting those big holes, so you can see what he's really capable of doing on his own.
"Because, as we know, in the NFL the holes are a lot smaller," Haley explained. "This is a big guy that can play like a big back, and yet also can get outside some and catch the ball."
The Steelers signed LaRod Stephens-Howling, who will be in the mix on third downs as well. At this point, Bell looks to have the best opportunity for touches of all the rookie RBs.
