Turncoat Coward can say these things because he doesn't own the responsibility of finding a replacement for Tua if he isn't extended and retained.
I mean, who does Coward think is going to QB the team when Tua leaves (under his scenario)? Miami isn't likely going to have a very high 1st round pick in 2024 and trading assets for Jonathan Taylor further limits their options in finding another QB. Is there a no-brainer upgrade that's going to be available as an unrestricted FA that the Dolphins can afford in 2024???
Coward never thinks things through.
Most of all, he's wrong about Tua not being extended if he has a big season. That's just his ego not wanting to come off his poor take.
