I'd roll with charles. He should get at least 15 carries and a few passes against a pretty soft JAX run D.
stewart needs to get to the goal-line to be effective, which is a risky proposition given the matchup.
miami's missing some key run-stoppers, but they're still a tough D playing for their lives, and the pats will throw and throw often, plus they rotate RBs.
