If he rolls off 8 quality games in a row it’s a no brainer that he comes back, unless the Carolina pick is #1 and you are in love with the top guy. Then you trade fields in the offseason. If he continues to flow between bad and good games, it all depends on the Carolina pick and which qb you like. Bringing Fields backs on final year, not picking up 5th year option and letting 2024 play out is not the worst option if you don’t have the ideal situation to replace him.
worst case is bears and Carolina picks are outside the top 5 and you allow poles to trade up for the new guy.
