No Bears make Bill Barnwell's top 50 trade value guys, only Cutler and Jeffery make the honorable mentions. http://grantland.com/features/nfl-trade-value-assets-part-2/ (this is only part 2) Kind of surprised Marshall isn't even mentioned. I get that he's over 30 and just signed a contract extension but the guy is one of the best 5-6 receivers in football and he's a very advanced stats friendly guy. Should at least be in the discussion with Cutler and Jeffery. As for the other Bears, Forte is past the standard RB prime, Long isn't advance stats friendly enough (based on FO at least), Houston just signed a big contract extension that lowers his value a bit and Briggs, Allen and Tillman are all way too old.
