The second overall pick in the 2015 draft, Mariota was benched in the third quarter of Week 6 last year after passing for 63 yards and two interceptions. He lost his starting job for good the following week and took just five more snaps the rest of the season as Ryan Tannehill led the Titans to the AFC championship game. Mariota's Titans tenure ended in March when he signed a two-year $17.6 million deal with the Raiders that made him the highest-paid backup in the league. He enters the season as the No. 2 to Derek Carr, but that's a big contract to simply hold a clipboard and it wouldn't surprise if he pulled a Tannehill - the underachieving free-agent looking for a new start who pushes out the lackluster incumbent. But Carr won't be as easy to dislodge. He's a highly efficient QB - even if it's built on dink-and-dunking - who takes care of the ball (eight INTs on 513 attempts last year). Plus, he's under contract through 2022. If Mariota gets his chance, though, he'll have a better supporting cast than he's ever had. Tyrell Williams is healthy, Hunter Renfrow showed promise in his rookie year and TE Darren Waller had a breakout season. The team drafted speedster Henry Ruggs (4.27 40) 12th overall, and 1,150-yard rusher Josh Jacobs returns ready for more passing-down work. A quarterback with similar passing numbers to Carr with the rushing upside of Mariota would make for a decent fantasy asset. Read Past Outlooks
