Preseason didn't prove anything with respect to Starks. It would have been premature to release him based on 15-20 carries in an offense run by a 3rd or 4th string QB behind 2nd string linemen and linemen who are no longer in the NFL. It might even be premature to give up on him completely based on 4 games so far, but they do need to be working on a contingency plan (and I suspect they have).
