If Harvin is such a great WR, what's the explanation from SEA in regards to not utilizing him in that manner? I'm playing a bit of devil's advocate here as I think that Harvin is a great talent....but I don't believe that SEA would have this potential top tier WR and not utilize him. Does SEA know something about his skillset/talent level/ability that we don't?
Far be it from coaches making bad decisions, right?
It's not like we're talking about the Raiders here. SEA has done a pretty good job of acquiring and utilizing quality talent for some time now. Plus, it's not like they didn't specifically target him and pay a fairly high price for him. I don't think they'd be a team to completely whiff on a player whom presumably the entire fantasy football world adores. Thanks for your input.
Touchy in here today. We already know Harvin can play traditional WR style. He's done it before. Maybe SEA has a different plan. Maybe he's a half step slow. Maybe he hasn't developed report with Wilson. Maybe lots of things but the conclusion you can't fairly make is that he's not a good receiver. We know he has been for a few years.
What's "tratitional WR style?" You mean downfield? Can't do that in SEA 2014 any more than they could in MIN in 2011.
Why? Neither Ponder nor Wilson has a deep arm. With Ponder, it was dumpoff heaven. Harvin's best season of his career, possibly, and only two downfield receptions the whole season. With Wilson, his downfield successes are almost entirely predicated on tall receivers winning jump balls, unless there's a totally blown coverage. There's a reason Lockette and Kearse have few catches, yet impressive highlight reels. It's because they're put in position where they have to make highlight catches, as part of the gameplan. Percy lacks the size to do that. If he's going to get wide open, it's going to be because he burned a CB on a deep route -- but he hasn't had a QB with the ability to take advantage of that situation since Favre -- which, not coincidentally, in 2010 accounted for almost every big downfield play of his career to date.
Harvin doesn't have the size or the tools to win those battles, and the other two WR's don't have much else. (Reference, if you like, the series of youtube highlight reels posted above, where the downfield "jumpballs" Harvin supposedly proved he can handle were against Hunter Hillenmeyer, and on a fade that any 6'0" WR would have turned into a laugher.

He's good, but he's limited in what his body will allow him to do in jump ball situations.
BUT, he's got best-in-league ability to do crazy things with the ball in space. So getting him the ball short and on sweeps and reverses, while letting the bigger, more physical receivers do the dirty work of trying to come down with Wilson's jump balls just makes sense. And the Seahawks do things that make sense, since Pete's a good coach.
None of that is to disparage either Harvin or Wilson. I'd take both over 90% of the players at their positions in the NFL. And all players are limited. Smart playcalling dictates that you use players in ways that maximize their strengths, and minimize their weaknesses. For SEA, that means Wilson isn't going to be taking many downfield shots with Harvin. Alas.
