Actually, forget this trade... lets send the Browns QB Tarvaris Jackson, WR Sidney Rice, RB Robert Turbin, + Oakland's 5th Round Pick for WR Josh Gordon.
Jackson would be a major upgrade over Weeden.
Rice and Turbin would be serviceable, one or both could be stars. Rice would restructure for 2014 and beyond as part of the deal.
Seahawks can then re-sign FB Michael Robinson to replace Turbin's spot, and move Spencer Ware to 2nd/3rd RB when he's healthy.
Seahawks get a killer WR corps with Gordon, Tate, Harvin, Baldwin, and Kearse for 2013.
Seahawks can re-sign Tate, and tender RFA Baldwin with the highest designation , then later trade Baldwin for a 3rd Round pick to the Colts.
Gordon, Tate, Harvin plus Kearse would still kick so much ass and be relatively cheaper over trying to keep Rice, Tate, and Baldwin together which they won't.
Its also funny the Browns are trying to pull a Colts for a top pick but their team is refusing to lay down, now they're ahead of the pack in the AFC north, just better roll with the punches and give the fans something to root for its been a long time since the Browns could compete for the Division.
