There's another thing. Even a really solid team can lose a playoff game. First, only one team can win the Super Bowl each season. Also, because the violence of the sport makes one-game playoffs necessary (instead of, for example, best-of-seven series like in baseball, basketball, and hockey), and crazy stuff can happen in a single game, the best team doesn't always win. Plus a single injury to a key player can completely mess up a team's plans for a whole season. There are ways a strong team that happens to be in a strong conference can even fail to make the playoffs.
The models that provide probabilities of victory (and let's include Vegas odds in that) for a given game, in the case of a severe mismatch between, say, a top title contender and a weak team that will have a top-three draft pick, still only give something like an 80% chance for the stronger team to win. Heck, make it 90%. That still means a team like the 2022 Bears can beat a team like the 2022 Gold Diggers one time in ten. When you look specifically at playoff games, where there's even more parity than in the league as a whole, the chance of an upset (the less-strong team winning) is pretty high, let's say 25% to almost 50%. Throw in a key injury or two, and an "upset" can actually become more likely than the stronger-overall team winning.
So in the end, the best bet, if it's "Team X" or "the field," even if "Team X" is the consensus favorite for the Super Bowl title that season, is to take "the field." And a lot of the .NET Eeyores know this, so their attacks on Carroll and the Seahawks front office are likelier to look good after the season is over than the prognostications of more-positive Seahawks fans.
