He's not being signed because of difficulties taking a physical ATM. Teams want to make sure he is healthy
Which team would he start for?
LV-Carr/Mariotta, KC-Mahommes, Den-Locke, LAC-Taylor/Herbert
Pit-Rothliesberger, Cin-Burrow, Cle-Mayfield, Bal-Jackson
Hou-Watson, Ind-Rivers/Brissett, Ten-Tannehill, Jac-Minshew
NE-Stidham, NYJ-Darnold, Buf-Allen, Mia-Fitzpatrick/Tua
Sea-Wilson, SF-Garrappolo, LAR-Goff, AZ-Murray
GB-Rodgers, Min-Cousins, Det-Stafford, Chi-Foles/Trubisky
Atl-Ryan, NO-Brees, TB-Brady, Car-Bridgewater
Dal-Prescott/Dalton, Phi-Wentz, NYG-Jones, Was-Haskins
It's really NE and Jax.
If we are going by the assumption that Cam is expecting $20 million to play, then it really limits the options. There are guys like Carr/Garrappolo who can get cut without a huge dead cap hit, but I don't see either team wanting to risk it with a guy who has been as beat up as Cam.
There are guys he's better than right now, but teams are committed to seeing what Mayfield, Darnold, Haskins, etc. do. If things go sideways for a couple of teams, they would then see what their young QB has to offer near the end of the season.
Does 2021 get much better with Lawrence and Fields, and whomever else may emerge in college? You'd see Tua, Herbert likely starting for their teams when those 2 come in.
