I can't see any team in the top 3 trading their pick straight up for Dak.
The Jags are cheap and will want to create offseason hype for Lawrence.
Jets have cap space, but also have the chance at getting Wilson and trying to rebuild with a new shiny QB with a much lower cap hit.
Miami has been rumored to Watson, but at least he's under contract for the next 4 years. Easier to retool a deal than trade for a guy on a 2nd franchise tag and work out a new deal.
I think there's a market for Dak, still injured or not. But I don't think we will be able to trade him and acquire a top draft pick and get the QB of our choice.
