Watson can throw from the pocket. He can throw on the run. He can get yards with his legs.
Have you watched him play?? He completes 67% of his passes. He is a top 5 QB by any reasonable measure and better than any of the guys you name. Other than Mahomes, you could make an argument he's the best QB in the league right now. Maybe I'd take Rogers and Wilson over him. I can't think of anybody else. And he's way younger than Rogers.
IMO, franchise QBs in their prime don't get traded so I think he's staying in Houston, but hell yeah I'd take Watson with Sean Payton.......
