Stafford didn't play well but neither did the defense, or the receivers outside of Calvin Johnson, or the Tight Ends, or the running backs not named Joique Bell etc.
The difference between Stafford and the guys there is that we've seen him put together a great year. Only Vick on the list really has had flashes of talent that lasted longer than a few games. Tannehill and Weeded were rookies so its natural they and the teams would struggle. The rest suck or aren't more than average.
