I'd rather keep Love, but if Love wanted a trade and other team was willing to trade their QB:
Mahomes
Lamar
Burrow
maybe Stroud or Herbert

It's not a long list. Love needs more games but he's been getting better and better lately. I hope he isn't a flash-in-the-pan type like RG3 (I don't think he is), but a lot of other smart people seem to think he's both good and a franchise QB.

I'd trade Minshew for Fields, but that's about who I'd trade for Fields. I think he'd be a great backup for Lamar, and might be good with the right offense. He might be good fit in ATL. You have to give him a good OL and cater your offense to his skills. CHI didn't really do that well, and they generally ruin QBs by rushing them onto the field with subpar surrounding talent. As it is, Fields is not a top 10 QB and I'm not sure if he will be. He might be Marcus Mariota (or other similar QB) v2.0.
