Not likely that the Bears would do the Chris Spielman/Lions thing, but Chico might be a good voice for the Halas family to listen to.
Seems to be universally respected in the football world, former Bear from the SuperBowl winning team, likely has lots of league wide contacts given all his time as a coach. He made a lot of bad decisions in Washington, but in theory that wouldn't be his lane.
Again, doesn't seem like a thing the Bears would do, but I wouldn't hate it. Rivera would be better than Kreutz or Urlacher. Cutler might be the most fun, ha
