I'm sure Palmer will take a bit less and play at least this year for the Raiders. Unless they can line up a taker elsewhere who will take the cap hit which seems unlikely...I'm sure he's here at least for this year.
Jerry McDonald just said on twitter he thinks Palmer is here for at least 2 more years. Palmer took a pay-cut last year, I think he will this year, too.
Despite it not being Reggie's guy this organization paid a heavy price for Carson and cannot just bail.
