If they decide not to trade Watson before the draft, we should seriously consider trading down from #2 and getting more draft capital next season. I could see the Texans being stubborn and testing Watson's resolve. And if that's the case, getting a 3rd 1st-round pick next year makes us the favorites for Watson next season.
It's a risk, but if they believe in Darnold, that's another potential option. Let Darnold be the guy, and then if Watson becomes truly available, we can push him aside later.
