I've been on record forecasting Watson to Miami, but recently my tenor has changed with more support from the Dolphins for Tua Tagovailoa and the Panthers' previous aggressive pursuit of Matthew Stafford. Carolina's roster on defense took shape relatively quickly in 2020, opening its window to be aggressive sooner. New GM Scott Fitterer has the eighth pick as one of his chips to play in a deal to acquire Watson.
Houston has no interest in trading him away right now, but we know this has already been ugly. If you ultimately trade away a franchise quarterback, moving him to a team you play once every four years is preferred to an in-conference foe (assuming the offers are comparable).
