In close quarters running, I might even give the edge to Price, although I think Love has narrowed this gap during the course of the season as he's worked on patience and hitting the hole versus relying on acrobatics. I think Love blocks a bit better, but that's also close. Kudos to the RB coach for helping them both develop.
The negative you can't prove is how good either would be without the other. I think they both do well because they aren't taking 100% of the plays. RB is grueling when you are it. So, hard to say how it would impact either if they were a full-time back.
