The Facts: Tagovailoa believes he can be the Miami Dolphins' franchise quarterback but knows he has to prove it with better play in Year 2. With the Dolphins in the thick of offseason quarterback speculation for the second consecutive year, Tagovailoa was asked whether he is convinced that Miami is all-in on him as the franchise quarterback. "In my mind and in my heart, I would hope so," Tagovailoa said Monday during an interview with Sirius Mad Dog Radio. "With the way things went last year, you always have to prove yourself to do better, and I want to do better."

Diehards Line: Tagovailoa is coming off a rookie season where he went 6-3 with a 64.1 percent completion rate, 14 total touchdowns and five interceptions. But the former Alabama star was replaced twice in the fourth quarter by veteran Ryan Fitzpatrick and struggled at times to throw the ball effectively downfield. HC Brian Flores told ESPN last month that he's "excited about the future with Tagovailoa," and the Dolphins believe in him. Dolphins GM Chris Grier also said last month that Tagovailoa is their starting quarterback and they are happy with his development. This offseason will prove if the Dolphins' strong public commitment to Tagovailoa matches their actions, with multiple options potentially available, including unhappy Houston Texans quarterback Deshaun Watson.
