Mariota, in fact, is his favorite NFL quarterback.
"It's true," Davis, with a smile, said on Wednesday while attending a Play60 event the day before the NFL Draft. "He is smart, he is very accurate and I like the swagger he has going on. He is very poised, and he is a great leader."
As for the possibility of playing in Tennessee?
"I would love it," said Davis, who visited Nashville earlier this month. "When I was there I met with the OC (Terry Robiskie), and he is real cool, real laid-back. The head coach, the GM, they seemed to like me, too. We kind of hit it off. Overall, it went really well, really smooth."
Davis, who also visited the Ravens, Eagles, Browns and Cardinals, is one of the top receivers in this year's NFL Draft. Clemson's Mike Williams and Washington's John Ross are also considered first-round picks.
All three players paid pre-draft visits to the Titans, and said they'd welcome a chance to play in Tennessee. The Titans have the fifth and 18th picks in the first round.
"I met Mariota before, and I like his style,'' Ross said on Wednesday. "He's quiet, and seems like he's a real good leader. He is all about football, and you like those characteristics in a quarterback.
"With his skill set, I think he has a lot of talent. And I think it would be a great opportunity to be able to grow with him. It would be a great place to play. I loved the facility, loved the coaches – had an absolutely amazing time with the coaches. It was great."
Williams, the only one of the three receivers not here for the draft, said during his pre-draft visit to Saint Thomas Sports Park he was impressed with the Titans as well.
"Mariota, he's a great quarterback,'' Williams said. "I feel like me and him could get together and do some amazing things. He can run it, he can throw it, and he is accurate with the ball. I feel like I could bring a threat to the offense."
All three receivers are different.
Williams is big and physical. He's nearly 6-foot-4, and he weighed in at 218 pounds at the NFL Combine before NFL scouts. He's coming off a season when he recorded 98 catches for 1,361 yards and 11 touchdowns.
Davis is an imposing figure himself, standing nearly 6-3, at 209 pounds, with good speed. Davis caught 97 balls for 1,500 yards and 19 touchdowns last season, and his 5,285 career receiving yards is an FBS record.
And then there's Ross. He's just 5-10, 188, but he can fly – he posted a combine record of 4.22 at the NFL Combine. Ross had a big year in 2016 himself, recording 81 catches for 1,150 yards.
"I think it just depends on what you're looking for,'' NFL Draft analyst Mike Mayock said of the Titans.
Davis said he's over the ankle injury that slowed him during the offseason. He said on Wednesday, "I'm ready to play right now."
Williams made plenty of stops the pre-draft process. Ross, after visiting the Titans, Eagles, Browns, Ravens and Bengals, said he's ready to find his new home as well.
Will one of them land in Tennessee?
"The most stressful part of this, for all of us, is not knowing where you're going to be and waiting so long,'' Ross said. "You want to be part of an organization. I think all of us are ready to find out where we're going to be."
