I totally agree. To the extent the underlying facts and opinions laid out in the piece are true, you see multiple examples of Sherman raging at the lack of accountability that Carroll's sunny-side-up routine tends to leave aside. If they're really treating Wilson differently (i.e., not demanding that he improve upon his errors), then I honestly can't see how other locker room leaders wouldn't have a fit over that type of atmosphere.
The oversimplified microcosm of the 6-6 tie game with Arizona lays out the thesis of the piece very well - Defense plays very well, carrying the team, offense / ST's scores 6 points and they don't win - Carroll says things are great and gives "participation trophy" level praise to everyone, including the OL who had been terrible.
Sherman goes ballistic because this isn't championship caliber behavior on an organizational scale.
We've seen Carroll maintain the Seahawks' system in the short term - they were nearly 2x champs, 3/4 division winners, playoff contenders since 2013, etc. There's now the question of whether the Seahawks can propagate their success forward systematically over the medium / long term. If they cannot, then you basically have to see the Seahawks' success as a personality driven result (i.e., they were lucky enough to catch lightning in a bottle with good young QB plus Lynch, Bennett, Thomas, Sherman, Chancellor et al. all on the team at the same time).
If Carroll cannot adapt his program to either develop new players to replace superstars, or build upon the remaining time they have with their superstars with a system meant to support them, then we can identify it as a failure on his part.
BB has been amazing at retooling the Patriots, especially in identifying weaknesses via very honest self-scouting.
