Wilson is a better QB right now but let's not pretend like those early Seattle teams were built around him in any form or fashion.
They won the Super Bowl in 2013 and made it in 2014 on the back of Lynch, and more importantly, their defense. A defense that was an all-time, generational type of defense. If you think Dak was a bus driver in 2016 or 2018 then I don't know what you'd call Wilson who barely even threw the ball 400 times until 2014.
Sure, Dak rode an elite OL/Elliott in 2016 but Wilson rode an elite defense, one of the best defenses of the last 20+ years for that matter, and Lynch while only throwing the ball about 20-25 times a game.
Since the offense, and team as a whole, have been built more around Wilson they haven't made an NFCC and are 3-4 in the playoffs since 2015, and the only QB's Wilson has beaten in the playoffs since then are Stafford, Luke McCown and Teddy Bridgewater.
What Wilson has done with a shitty OL and so-so receiving options has been impressive, but I'd argue earlier in his career he had an even stronger infrastructure in place than Prescott did with the defense they had and Lynch, not to mention a competent coaching staff.
Put 2016-18 Prescott on those 2012-14 Seahawks teams and I think you'd get mostly the same result.
