I agree, and it'd really make our run game dynamic and a challenge for defenses.
I'd throw away age with Shady. He apparently works out as hard as anybody and the main thing is he doesn't take shots like the average RB. Very very rarely does he take a big shot because of his running style, I think he has 2 elite years left, he showed zero signs of slowing down to me and adding a legit complement can preserve Shady and make the defense worry about 2 completely different running styles. Shady runs so unique, it can throw a defense off n will help Shady's production as well
