The Facts: Mariota looked composed and was mostly mistake-free in his first training camp practice leading the Tennessee Titans. Between seven-on-seven work without lines and 11-on-11 team work, he was 13-of-18 and didn’t throw an interception.

Diehards Line: His teammates offered the same sort of solid reviews they offered during organized team activities and minicamp. "You could tell he was training this offseason, really in the playbook," tight end Delanie Walker said. "He called the huddle with poise, said the plays like he knew them, ran the offense very well. That’s exciting to see when you’ve got a young quarterback coming in and ready to go." While fantasy owners won't -- and shouldn't -- be clamoring to land Mariota this season, those interested in Walker and the rest of the Titans' receiving corps will want to watch the newcomer's progress. ... For what it's worth, ESPN.com's Paul Kuharsky notes that Kendall Wright is clearly the top receiver and Hakeem Nicks got the bulk of the work opposite Wright. But the second snap of many series featured Justin Hunter and two new guys, Harry Douglas and Dorial Green-Beckham.
