Why do people throw around the term "generational" talking about Wilson? He's never been even close to being the best QB in the league over a single season, nor over the extent of his career. I mentioned both things because I can imagine a situation where a QB was always in the top five, but never #1, and then over a ten-year-or-longer stretch was the best overall, because it was different guys who were better than he was in different seasons, but that did not happen with Wilson.
"Generational" means something like "once in a generation." I say "something like" because it's pretty clear that Manning and Brady were both that exceptional, but happened to play at roughly the same time. In any case, Wilson is pretty clearly not that special. "Above-average"? Sure. "Excellent in some seasons"? Absolutely, with Pete Carroll and his staff finding ways to get the most out of Wilson's strengths while minimizing the effects of Wilson's weaknesses (until "let Russ cook" gave us ten Wilson turnovers in three games). But "generational"? NOT EVEN CLOSE!
Wilson has been the Seahawks' best QB in terms of career value by a pretty wide margin. I would say it goes Wilson - giant gap - Krieg - Hasselbeck - Zorn. There's probably a pretty sizeable jump between #3 and #4 too, if I'm being really honest, but my #4 was also my first childhood sports hero, and I own a throwback jersey with his name and number and wore it to my first-ever Seahawks home game in 2019 (I had previously gone to Seahawks games in Foxborough in 1984 and 1986). If anyone wants to argue about who's second and who's third, I'm not gonna argue too much about it, because I think there are probably pretty good arguments for switching those two, but I think there are good arguments for putting Krieg ahead of Hasselbeck too, and it's difficult to be sure because they played in different eras.
In any case, "all-time best Seahawks QB" is clearly very different from "one of the greatest NFL QBs of all time." And I think it's very clear who the all-time best Seahawks QB (in terms of total value in his time on the Seahawks) was.
The Seahawks coaching staff was able to do some really great things with Wilson as the starting QB. The team never had a period of consistent winning like this before. Like others in this thread, I'm in my fifties and I started with the Seahawks as a grade-school kid in 1976. I remember things like the magical 1983 season, but I also remember the 1990s.
The current dumpster fire in Denver with Wilson "unshackled," coupled with the Seahawks' strong offense with a QB nobody wanted (example: Seahawks are fifth in offensive points per game, Broncos are 32nd) is fairly strong evidence that not only were Carroll and the Seahawks staff not holding Wilson back in 2012-2021, they were getting the most out of him. I'll be the first to admit it doesn't prove that, but it suggests that pretty strongly.
