Does seem a bit strange, but a number of reporters have mentioned it being in Cutler's contract. I suppose you could sell it as being needed in case the team ends up with a Brett Favre-like situation in the last few years of the contract. A young QB ready to take over and an ancient vet still under contract wanting to wring a few more years out of his career. It's an incentive for the team to release him and let him look for a home elsewhere, even with a team unwilling or unable to assume his remaining contract via a trade.
