Looking back into this, it looks like Herbert still has an 86M dead cap hit next year. I'd guess he'd have to be absolutely terrible all year for them to want to part ways, and if he's terrible all year, then we're probably looking at another Kyler Murray situation. As much as I'd be interested, I think this is a dead end.
Also, Joe Burrow has a 72M dead cap hit, Josh Allen 147M, Patrick Mahomes 183M, Lamar Jackson 74M, Trevor Lawrence 104M, Jordan Love 83M, Jared Goff 79M, Jalen Hurts 104M, Dak Prescott 131M, Baker Mayfield 95M and Brock Purdy 79M
Looks like the only two veteran QBs under a (non rookie) contract that won't cause the other team to make a Tua move and eat an intolerable amount of money are Daniel Jones and Sam Darnold. Where have I seen those guys before?
Also, Stafford is only 39M dead cap. So I guess, we've seen much worse. But then you'd have to start inventing reasons for the Rams to move on. And Ty Simpson isn't even dressing at the moment. Also, Malik Willis is at 39M. I don't even want to talk about that.
