Humphries said the time the two players spent in Oregon was well worth the trip.

Humphries, who played at Clemson, had never been to Oregon before taking Mariota up on his invitation.

"Just being able to sit down and eat breakfast and dinner with him, play golf, you know him a lot better than just walking around in meeting rooms and the locker room," Humphries said. "It was good to share that experience with him and really get to know him."

Earlier this offseason, Mariota discussed the impact Humphries could have on the team on the field, and in the locker room while working with younger players.

In 2018, the 25-year-old Humphries had a career high in receptions (76), receiving yards (816) and receiving touchdowns (five). The 5-foot-11, 195-pounder became Tampa Bay's top slot receiver while catching 219 passes for 2,329 yards and nine touchdowns over the last four seasons.

"I think having conversations with him, being around him now, you understand how savvy and smart he is as football player," Mariota said of Humphries. "I think that presence for that young group of receivers will benefit all of those guys. But I think Adam does a great job of just coming in, learn the offense as much as he can so that he can hopefully lead those guys and do his best."

Three days into training camp, Mariota-to-Humphries has been a nice combination.

Humphries looks around and sees a lot of options for his quarterback, in addition to himself. The transition to Tennessee, he said, has been great so far.
