I'm hoping that I don't get bashed for this because I'm a Rams fan....but if I do, oh well. I like your board and I have an opinion about this, so I'm going to share it...
I think the most difficult thing to figure out in the NFL is whether QBs make WRs good, or WRs make QBs good; or if it's 50/50. I'm willing to bet that all of us have opinions that go both ways: I personally think that Peyton Manning made Brandon Stokley a 1,000 yard WR, and I think Tom Brady made Wes Welker a great player (didn't do much with a bad QB in Miami). On the flip side, I think Kurt Warner was made by Bruce, Holt, and Faulk.
Complaining about a QB not having enough weapons automatically means he's not elite IMO. Elite QBs raise the level of play, and I've seen enough of Doug Baldwin to be fairly confident that with Peyton Manning, he could be a 1500 yard 10 TD WR.
So IMO, Wilson is excluded from the elite category. But where it gets really impossible to gauge these guys is when you factor in the offense they play in, all the players around them, and what they are asked to do - this last part, none of us know - because we are not in the film room or on the sideline with these coaches and players.
Here is what I see when I watch Russell Wilson play: a very good player, unique in his ability to avoid the rush but simultaneously takes too many sacks. The offensive line does get beat, but they also provide him with 10 seconds sometimes - way more time than any NFL QB should expect to get. I know there are metrics that say your offensive line doesn't pass protect well, and I don't want to argue that. But when I watch Wilson play, I see a guy that doesn't read defenses as quickly as elite QBs, doesn't get rid of the ball as quickly, and takes too many sacks for someone with his athleticism.
His passer rating thus far I attribute to him being a good player and the offense he plays in. I believe having a good defense helps his game as well. I believe people give him too much credit and not enough blame, the opposite of what happens to most QBs, because Seattle is not a pass first team. The Seahawks are in a position where they have to sign him, but doing so might prevent them from getting back to the superbowl - I'm sure the Patriots, at the height of their dynasty, thought they'd win several more. They were certainly picked to. Took 10 years for it to happen though.
Finally, when assessing NFL QBs, I look at it like this: in what order would I "draft" these QBs if I was starting a franchise from scratch. You can point to stats all day, but at the end of it it's everyone's eyeball test and bias that truly influences their opinions. Wilson is way down on my list of QBs to start a franchise with, because I don't believe he is capable of shouldering the load of a franchise. I can cite specific games, but he's had good games and bad games. His doubters will point to the NFCCG against Green Bay, and his supporters might point to the game he had in St. Louis against the Rams (a great performance) - but at the end of the day, how good of a player he truly is won't be proven for years - QBs, specifically, are a product of what is around them. You say bad Oline, I say great running game. You say bad WRs, I say great defense and special teams. It all comes together to play a large role in the success or failure of a QB....I hope he does get a $20 million contract, but I wouldn't do it.
