He had a good year for almost any starting quarterback in the NFL, including Phil Rivers and Carson Palmer.
It's not like "the OC in Seattle," whose name is Darrell Bevel, is Mike Martz, Mike Shanahan, or some other offensive guru who can turn chicken feathers into chicken salad. Bevel's one impressive season as a coordinator was 2009 with the Vikings, when Brett Favre (another pretty talented QB) was running the show.
The big knock that I totally understand that you're not (IMO) articulating very well is that Wilson was 25th in the NFL in passing attempts (393) and 40th in the NFL in attempts per game (24.6!). To put that in some perspective, Russell Wilson attempted just 50 more passes than the Arizona Cardinals had running plays last year.
Pretty much everyone is saying that he has to do it again; there's no question of that. The other thing that I think Chopper alludes to, but I want to make explicit, is that Seattle got Wilson with a third-round pick having gone 7-9 or something the year before. Wilson walked into a much better, more complete, more competitive team than either RG3 or Andrew Luck or Ryan Tannehill, including having a draft class around him to make him successful.
I think that Chopper's pushing on RG3 a little bit unfairly. RG3 had to work with a team that wasn't very good, and didn't have much support from the draft (because of the trade) or free agency (because of NFL-provided cap penalities for miscreance during the uncapped year).
I will specify a bit on this. I rank RGIII behind Kapernick, Luck and Wilson for a couple reasons, not all of which are his fault.
1-I think Luck is the next great QB we will see. All decade level of player. People may not agree, but that is how I feel which is why he ranks #1.
2-Mike Shannahan makes mobile QBs really good, really quick. He got great production out of Plummer and Cutler, and used their mobility to get them into great positions to make plays. Shannahan also got 3000+ yards out of Rex Grossman. Basically, Shannahan gets the most out of his QBs, and RGIII benefits from this.
3-RGIII is more athletic than Kapernick and Wilson, but he is not as thick as they are. Wilson seems to avoid contact better and Kaepernick has a better body to stand up to contact. RGIII has to show me he can be smarter at avoiding hits before I rank him higher, because those hits will translate into injuries with his frame.
What has impressed me the most is what all four of these QBs has done when you look at their supporting cast. Sidney Rice, Golden Tate, Michael Crabtree, Reggie Wayne, TY Hilton, and Pierre Garcon are the most notable receivers that these guys have to work with and none of them are great weapons. Crabtree has been incinsistent, Wayne is over 30, Hilton was a rookie and Garcon was injured for the majority of the year. In terms of running backs, Frank Gore, Marshawn Lynch, Vick Ballard and Alfred Morris? TEs get even worse with Vernon Davis and a injured/rookie/drug user mix of Zach Miller, Dewayne Allen, Cody Fleener and Fred Davis.
I am excited to see how these QBs all develop as they are all pretty fun to watch.
