Jameis Winston - contract

So if he has a season like last year, or he has a slightly better season but still leads the league in turnovers, do they give him a monster extension (30 mill a season)? Or do they let him walk and the Bucs draft a guy like Tua? If he shows he is a glorified game manager, is he worth all that money? Or do the Bucs rebuild entirely under the guidance of a new GM which the Bucs will almost certainly have next season? He hasn’t been to the playoffs and hasn’t shown much development in the last few seasons, very interesting scenario.
