Hendy gets dinged up and doesn't seem to get stronger as the game goes on. The guy had holes you could drive a bus through in college, in the pros the hits and running into constant contact seem to wear on him. That tells me change of pace. Really good back but change of pace is definitely where he'll do his most damage in his career at this level.
The horse types get stronger as the game goes on and tend to take over late. Akers has a chance to be that type of back based on the fact he stood up to running into walls of defenders over and over ad nauseum. It's why the Rams wanted him. Stay tuned too because it's coming.
