The real question is where is Watson willing to go. That will be the biggest determining factor.
The best situations
Indy
SF
Rams
Balt
Dallas
The best offers
Jets
Jags
Dolphins
Balt (not that they are interested, but Lamar is a player Hou would be interested in)
AZ (same as above)
Chargers (same)
And here is really the other question. If Houston doesn't love Zach Wilson, Tua, Darnold or fields, I expect they would contact teams who have a QB they could sell to their fan base. Herbert, Lamar, Kyler, and Burrow are probably the beginning if the Texans are looking a options. Young and cheap and exciting. Dak is a possibility though the injury hurts.
As Watson has the power to decide you have to think it's one of the top bunch than the bottom bunch.
Rams are out for me as I don't think they have the cap or the picks to do the deal. I considered Dallas, but then they were too cheap to pay Dak so I don't see them taking on that contract.
The Ravens are all in on Lamar, don't see that changing. Colts would be the perfect spot for Watson if they can get around the division rivalry. I like the Niners for him too but their scheme would be a waste of Watsons talent I feel.
Could the Giants be in? They don't seem sold on Danny Jones.
