Ronnie Brown is gone. So is Ricky Williams. Newly imported Reggie Bush can't handle a heavy workload, and the Dolphins don't want Chad Henne throwing more than he must. That means Daniel Thomas, a second-round pick out of Kansas State, could be the man in Week 1. He should pile up the carries and has the frame to be a workhorse. He'll be key in goal-line situations, where the Dolphins don't have another clear option. Part of the reason Thomas can have early success is because this offensive line looks built to support a solid running game, and rookie Mike Pouncey will be a big part of that. Pouncey should line up at center, and went extremely high in the draft for that position. But he has a similar skill set as his brother Maurkice, who was a Pro Bowl center last year for the Steelers.
