As a lot of people have already said, there is a reason that Pete Carroll and John Schneider traded 3 draft choices to get this guy.
See if this puts things in to perspective -- last year, Percy Harvin was #5 in the NFL in
Yards After the Catch (he gained 551 YAC) at a clip of 8.9 YAC. He had 677 Yards in total on 62 Catches and was being talked about as being an MVP Candidate.
Now think about all of that for just a second. That was on a Minnesota team with a QB (Ponder) who had a crappy arm. The Viking Offense with him was basically to just throw little smoke screens to him at or behind the Line of Scrimmage and let Percy do his thing -- and the numbers absolutely show that.
The average distance of the passes thrown to him (through the air) last year -- just 2.03 Yards/Reception. 551 of the 677 Yards gained were all on Percy. In other words, last year all you had to do is just get him the ball ... and he was an almost automatic instant 1st Down.
Imagine what he can do with a QB in Russell Wilson who has a great arm and is legitimate playmaker. My maniacal evil mad scientist laughter just won't die down over the prospects over just how much he changes how teams will defend the Seahawks. And you saw that in that Minnesota game, as the DB's all of a sudden began playing off of Seattle's receivers ... and guys like Doug Baldwin all of a sudden found themselves having a lot more space. They're fully aware of who Percy Harvin is and what he can do. If Harvin actually can play ... I think you'll see a lot of what's ailed the Seahawks receivers in terms of their troubles of getting open of late start to disappear.
