I'm worried he'll be on fumes come playoffs with his "bell-cow" workload but man:
1) for a guy not considered "large" or a thumper... he does not shy away from the contact that he knows is coming at the end, and is always churning for that last bit
2) RE: his workload, I'm sure he's begging for it/insisting. He WANTS to be known as a a top 3 RB/THE RB in the league, and has said he wants to be out there all the time. Love his energy, even when he's pissed because they pull him and his TD goes to Allen or another RB.
