We haven't been a SB contender since the SB loss.
Once we lost our depth, and started to build our team out in a direction that did not correspond to Pete's preferred playstyle that was over.
But do we need to be in a SB to be considered a success in a season?
We have consistently been one of the better teams in the league for near a decade.
You can be the Marlins, win it all and vanish shortly thereafter...or you can be like the Steelers and Seahawks. Consistently dangerous, consistently competitive and never really overmatched in any game (outside of the playoffs of course).
Unless you are SB or bust, that is still a hell of a privilege to be a fan of.
Much of that success was falls into 2 phases:
1 - The LOB phase
(which should probably be broken into Lynch and Post-Lynch eras)
When we had LOB, Lynch, + Wilson we were clear SB contenders. (Before we traded Unger & lost Tate really)
2 - The Wilson phase (Not SuperBowl contenders but still upper tier team)
Less trustworthy defense offset by fantastic QB play to save games
We were clearly no longer SB anything the moment we kept playing like we had the LOB when they were gone. But the moment Wilson is gone, we probably aren't even a playoff team.
Carroll was never an X & Os guy, he was always about finding better 'Jimmys and Joes'. And for the most part he did a great job with that. It masked his tremendous weaknesses at tactics and strategy. But he hasn't delivered on his supposed strengths for a few years now. Likely lost them.
We hopefully have Wilson for one more year. Enjoy it. Doubt we are a playoff team even then given how much better everyone else in our division has gotten + the discord recently. But, for a long time, this team with Wilson is going to be better than any version without him unless we get a magical coaching change.
