OK, granted : so, we had only one year of actual/efficient QB insurance before the JimmyG era, and about 13 seasons of "No Brady No Hope" situation. That was my point, we have been a pretty successful dynasty for 15 years (and counting) without any solid back up plan in case of season-ending injury of our starter, assuming that whoever the backup would be, he wouldn't be good enough to take us to the Big Game. So if Jimmy had to leave, I would be OK to keep going all in relying on Brady's health. That being said, the decision to be made about Jimmy G is not so much about getting rid of a capable backup for the remaining of the Brady era, but getting a heir apparent in the good timing.
