make plays with your arm. That's what he did. Hill used his legs to make plays with his legs. Detmer talks about Hill using his legs as his own type of check down. Mangum uses his legs to buy time to find a target to throw to. The same result of a first down is expected. And I'll take the arm over last year's running. Hill got chased down a LOT last season. He'd choose to run when he had targets open, and end up getting caught. Happened over and over against UCLA.
Oh and Mangum still has some wheels. He can run. He just doesn't want to and believes he doesn't need to. 2015 was just awkward because he wasn't in great shape and he had that hamstring injury. He's not a running QB, but he's not Manning out there.
