Cassell deserves more snaps in the preseason before any final judgement is made, but if he continues to disappoint, the following scenario might make sense. At the end of training camp cut Cassell (he's not going to be of any trade value) and cut Guttierrez (assuming continued lackluster performance). Place Guttierrez on the practice squad, assuming the othe 31 clubs pass on him. Keep O'Connell as Brady's backup and as the primary developmental QB. Have Vinnie on speed dial should the unthinkable happen to number 12. The Patriots under Belichick have kept only two quarterbacks at least once. Advantages: clears a one roster space for an additional running back, rookie linebacker, or tight end. Gives O'Connell more snaps in practice and speeds his understanding of the offense. Disadvantages: Vinnie is mighty old, and even though he knows the offense, during the season he would be coming in completely cold. There are probably better veteran backup QBs than Vinnie out there, who if they were brought in during training camp and given time to learn the offense, would give the Pats a better chance of victory in a replacement role.
