Regression. Sophomore slump. Defenses figuring him out. I've heard these mentioned more than once regarding Russell Wilson. Is it true? Well, let's look at some numbers from the last five games he played last season and the first five games of this season.
2012
83/125, 66.4%, 1198 yds (239.6/gm), 9 TDs (7.2%), 2 Ints (1.6%), 4-1 record
2013
74/127, 58.3%, 997 yards (199.4/gm), 8 TDs (6.3%), 4 Ints (3.1%), 4-1 record
In both cases he played 2 home games and 3 road games. Even played them in the same order, R, H, H, R, R, and in both cases the team won the first four and lost the fifth. 2012's opponents were a bit better, with a combined winning percentage of .593 compared to .417 for 2013's opponents.
So, against arguably inferior opponents Russell is completing 8% fewer of his passes for 40 fewer yards per game and he's throwing interceptions at twice the rate. Why? Is it his ability? The offensive line? The playcalling? The receivers?
Personally I think it's a combination of factors and I trust in Pete Carroll, Darrell Bevell, and, most importantly, Russell Wilson to sort this out and get back to playing better and more consistently in the passing game. What say you?
