he doesnt dip before contact. Once contacted he does, but hes already taken considerable impact at that point. passing the line especially you see a lot of arm tackles, you take a lot of abuse on the hip and legs running through arm tackles up right.
He might. He doesnt have the first step explosive quickness, but has strong top end speed. He has great aggression and toughness. I dont know if he has the vision as a runner, he hasnt run the option / zone read well at all to date. Trent richardson comes to mind, but with better top end speed but with a greater toughness.
