Russell Wilson averaged under 200 passing yards per game. Let's compare that to some other NFL QB's.
Drew Brees #1, 323.6 YPG
Matt Stafford #2, 310.4 YPG
Tony Romo #3, 306.4 YPG
Ton Brady #4, 301.7 YPG
...
Andrew Luck #7 273.4 YPG
...
Ryan Fitzpatrick #24 212.5 YPG
Chad Henne #25 208.4 YPG
Ryan Tannehill #26, 205.9 YPG
...
Matt Cassell #29, 199.6 YPG
Jake Locker #30 197.8 YPG
Russell Wilson #31 194.9 YPG
Kevin Kolb #32 194.8 YPG
Mark Sanchez #33 192.2 YPG
Christian Ponder #34 183.4 YPG
He only averaged 24 attempts per game. Matt Stafford the leader in attempts averaged nearly twice as many every single game. RG3 averaged 26 attempts per game, Alex Smith 21 per game, Kaepernick 17 attempts per game. So if you have a running QB or a QB on a stacked roster you are going to be throwing a lot less. Even if you added every single rushing yard Russell Wilson earned and don't count other QB's rushing then he is still only at 225 per game which puts him in the same range as Ryan Fitzpatrick - a now backup QB.
His competion percentage was good but it's easier to be efficient when you are passing less and on a good team with a good defense. It it's not there you don't have to force it. Matt Schaub is a game manager on a good defensive team that runs the ball, he also completed 64% of his passes and he averaged 250 yards passing per game. I don't have to see Schaub's ugly mug on ESPN all the time.
Wilson's TD to INT ratio was great but he was on a good team with a great defense that forced turnovers. You get the ball in good field position and it's different. He doesn't have to take crazy risks or throw passes into coverage. Also that TD pass to Golden Tate was a complete gift. His numbers were again similar to Matt Schaub.
I am not saying Russell Wilson is a bad player, but at this point in his career he statistically looks much more like a game manager on a good team. ESPN has created this caricture of him that he's a mobile QB, on a crappy team who is willing his team to victories by throwing, running and doing whatever is neccesary. They talk about him like he's already elite. The stats don't support this notion at all. Seattle had the #1 scoring defense in the league last year and was #4 in yards give up, Russell Wilson's stats were at the bottom of the league for starters. Do you remember when David Garrard had some pretty good stats? In 2007 David Garrard threw 18 TD passes with 3 interceptions and his record was 9-3 as a starter. Was he really great at reading defense or was he very risk averse and throwing lots of dump offs to MJD?
The point is that Russell Wilson still has a looooooooong way to go. If you cut out the ESPN hype and stopped comparing him to RG3 or Cam Newton, right now he's a short game manager QB on a team with a great defense.
