Tua under McDaniels is the most recent version of Jared Goff under McVey.
So long as the coach and the scheme do all the processing for him, he's amazing.
When the system runs perfectly, he's perfect.
When the League caught on, and started running bracket coverage on whoever is in motion and press-man everywhere else, the system falls apart.
Then because Tua is the golden child, and Miami has about a billion dollars locked up in WRs, they MUST try to throw their way out of the jam. Against mediocre teams, they can. Against everyone else, they can't.
