Not sure there have been many of those. Usually MVP is on one of the teams with the best record. And to be all-pro QB you have to have more than 8-8 record. Not going to give you all pro and pass on QB with 13-3 record. Just doesn't work that way. Now pro bowl maybe.
Yes, I see now only our very own Dan Marino has been named an all pro with a non winning record at 8-8.
