"I honestly think that is a good rule," Tagovailoa told CBS Sports' Zach Gelb. "I'd say because when you go the NFL, you're playing against grown men. This isn't something that you need to take lightly. And you've got to take into consideration that it's a job. It's a job when you go to the NFL, and just being able to stay in college for another year, for me - being able to hear all these people, these speakers come and talk to us about how to be accountable for your money, how to be accountable in things you do, you learn so many lessons before you even reach that stage to where when things do happen, you've heard it from other guys. You have contacts to go to. Just little things like that."
If he was eligible for the 2019 draft, Tagovailoa would be heavily favored to be the first quarterback selected. Basketball players in his position are able to capitalize on such status, and can enter the NBA draft after one year in college.
But Tagovailoa suggested football players face a larger gap when they jump from the amateur ranks to the NFL.
"I hear guys who have played in the league that come back that are from Alabama and they say you can't compare the two," he said. "College is definitely a lot different than the NFL, in all aspects, in every aspect. So I think the three years is fine for me."
Tagovailoa threw for 3,966 yards with 43 touchdowns and six interceptions as a sophomore, finishing second in voting for the Heisman Trophy.
