Jets, Patriots, Bills, Dolphins.. Do you think any of these teams would be interested in Dak? I don't see any.
Titans, Colts, Ravens, Texans. Maybe the Titans? If they think Dak is a huge upgrade, neither are elite.
Bengals, Browns, Steelers, Ravens. Just the Bengals for now.
Chiefs, Chargers, Raiders, Broncos. I don't know what they plan to do with Rivers. If they sign him again, which I believe will happen, they're out. Raiders look like they are keeping Carr since his deal isn't too expensive now. Broncos drafted Drew Lock.
Eagles, Giants, Commanders. We can safely say no for any of these teams.
Bears Packers, Vikings, Lions. Same goes for this group.
Bucs, Saints, Falcons, Panthers. I put the Bucs in the same category with the Titans. Are the Saints moving on from Drew?
Rams, 49ers, Seahawks, Cards. These teams are also out.
I'm getting 3 teams. One likely candidate and two iffy teams. I don't know where you're getting 10-15. Even if you add the aging vets like Big Ben, Brees, and Rivers, we only get 6. And those teams IMO are highly doubtful. Most of the other QBs are signed.
