While he does have trouble with dropping passes at times, he would be a great aquisition if that ever transpired.
Seattle does have a lot of talent at WR with Deion Branch, Jackson, DJ Hackett, Bobby Engram, and Nate Burleson.
I agree with Simon if we could get him for a 3rd i'd be really happy. I also would love to grab Hackett if the seahawks only offer him the low tender. Either one of those guys would make me feel better about our receiving core.
