1-A team with no QB and need to do something ie San Francisco, Minnesota etc
2-A team with an established QB who will want Vick to have about 15-20 snaps(not all of which he will touch the ball) ie New England
O'Connell was taken last year as a project and either long-term solution or at very worst stop gap for life post-Brady. It would be very similar to what the Dolphins done this year. Chad Henne is almost the future QB but on game day Pat White will dress as the #2 behind Pennington. If Brady was to go down with both O'Connell and Vick I would suspect O'Connell would be the starter because the offense is very complicated and Vick wouldn't even have a full offseason to get used to it, plus he is in no shape to start for any team at the minute.
