IMHO, just off the top of my head...
QUARTERBACK
Trent Dilfer (maybe) -- Hasselbeck has finally begun to bloom into the quarterback Holmgren envisioned when he traded for him. Trent wants to start. He doesn't have THAT big of a contract, but I think he's getting paid better money than Hasselbeck.
Kurt Warner (almost definitely) -- Astronomical cap figure, bad throwing hand/shoulder. PR battle between his wife and the organization. New rift between Warner and Martz. Emergence of Mark Bulger.
Kordell Stewart (very likely) -- We all know why.
Tim Couch (possibly) -- For some reason, Couch has never really clicked with the Cleveland fans. Probably because he was forced to start as a rookie and has had some growing pains. Kelly Holcombe has made a very strong argument to be the #1 guy for the Browns, and Couch is carrying a #1 contract.
WIDE RECEIVER
Keyshawn Johnson (possibly) -- I keep hearing how Keyshawn isn't happy in Tampa, and there are rumors flying he would play for Parcells in Dallas. Johnson carries a huge contract and quite frankly I think the Bucs could get the job done starting McCardell and Jurevicious, especially if they pick up a decent rookie WR in the offseason.
Donald Hayes (?) -- Seems like I heard a rumor about this.
Sorry, Meat, that's all I've got for now.
