Why would lost afccg or lost SB be a subpar season? For anyone.
Because, Tom Brady.
If they think it's time in Foxboro, it would be a much more acrimonious parting to say "thanks for another trophy, see ya." It would be
such a straightforward statement of "I don't care where you are and what you're capable of, I can guess where you're gonna be."
Perhaps a lost SB is a stretch. On average, he "only" wins the SB every third year. He plays in the SB roughly every other year. For Brady to date, missing the AFCCG is "sub-par," as he's taken the team there 9 times out of 15. So let's call making the AFCCG the over-under.
How many times have we said in this thread "...who just won the Super Bowl...?"
Immediate proximity to another SB win makes the calculus very difficult; after all, winning is the goal and parting ways with him at the top of his game means you are
purely relying on the breakdown of all other quarterbacks at that age to make your decision.
But I exaggerated for effect to an extent. On the down side, this isn't a guy who goes 10-6, goes one and done in the playoffs, and gets a big fat raise because he's going to take that next step any minute now. If we see an 8-8 season, that's an unprecedented decline. It's hard to see 8-8 out of Brady coupled with a grand statement of "He's our QB into the foreseeable future, good luck to Jimmy, there's only so much room at the top."
I don't think Garappolo is a very secure choice of "next man up" based on that little problem of having to be on the field to play. Nobody here thinks that JG or any other QB is Brady. The question is whether BB thinks he can build around JG, or whether he considers him an expendable JAG. His moves to date suggest that he does not consider JG a JAG.
Around here I see people occasionally talking about how the "real" next guy is Jacoby Brissett, but I haven't seen anything impressive out of that guy.
