re: Anyone else secretly believe Darrel Williams could be as good or better than LF?

LF will be the better back only if he is used right. If they only bring him in say 1 series a quarter the defense will key on him. I think in order for him to be a all American type back you need to feed him the ball more then just a rotation back. His greatness is the ability to break long scoring runs. Just 10 touches a game want allow him enough chances to do that.
All great backs from Jim Brown to Barry Sanders were the feature backs. If they were in a rotation with just 10 carries a game they would of never became hall of famers. LF greatness is in breaking the one run a game that most backs never have but 1 a season or 1 in a career.
