We have Ingle Martin too. The smart thing to do would have been to say 'fuck you' to the wishes of the fans (who own the team), the GM, the head coach, and Brett's teammates so we can get moving on the Rodgers era. If he gets hurt, again, already, during one half, there's the future legend Ingle Martin in the wings.
After a a 4-0 December with a young team that will only be better next year, the best bet is to dump the experienced qb in favor of rebuilding all over again.
