I was commenting on you saying speed caught up to Duke as you were implying he isn't doing well. Another poster said he was a scat back.
Duke has done well in the NFL and was rewarded with a nice contract.
You guys do realize that Duke has gone for 965, 1003, 1058 yard from scrimmage his first 3 years and just signed a 3yr 15m extension (11th highest paid RB in the NFL).
