I don't remotely think that either front office is sold on Kyler or Fields being the "QBOTF", but the contract situations are as far apart as imaginable.
The Bears are faced with picking up Fields 5th year option or extending him, neither are appealing given his career thus far. If they are not sold on Fields they can easily cut bait at virtually no cost at all.
Meanwhile, dumping Kyler this off season basically dooms us to a 2nd straight year of sitting out free agency or any new significant contract commitments.
The Bears have a lot of options, especially with the #1 pick in hand... we don't. We can ride out another season of Kyler and hope he returns to his form from 2 years ago, or doom some poor rookie or low cost, vet player to play with a bare bones offense because we used all our cap space to eat Kyler's contract.
I'm not sold on Kyler as the long term guy at all, but I think the realities of our situation basically locks him in for one more season. If we had the #1 pick and if some college QB looked like a can't miss superstar, it probably would have changed that dynamic... but that didn't happen.
