I don't see how anyone can objectively say that Tua is what's wrong with this team.
I absolutely can point at poor personnel choices by Grier, Flo's coaching decisions, let alone his dual OC and cycling through them.
Myself, I don't want them to trade for Watson at the rumored cost. Wanna make Grier the scape goat and hand the keys to Marvin Allen, sure. Insist to Flo that has stability in the OC etc... I'm on board. Hemorrhaging the future by trading for Watson screams a last ditch effort to save jobs, and isn't the best way forward IMO.
