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

Past Fantasy Outlooks

After four seasons and 55 NFL starts by Mariota, the Titans still don't seem to have any clue if they've found their franchise quarterback. Injuries, poor coaching and a lack of receiving talent have all played a role in that equation, but it's also hard to shake the feeling that Mariota simply isn't anything special. He took a step back in 2017 after a promising 2016 campaign, and his massive growth in completion percentage last season (68.9 percent) was offset for practical purposes by career lows in yards per completion (11.1) and sack rate (11.3 percent, highest among qualified QBs). His average depth of target was a mere 7.6 yards, fifth lowest in the league. Tennessee took an aggressive approach to upgrading its offense this offseason, signing slot receiver Adam Humphries and guard Rodger Saffold before drafting wideout A.J. Brown at No. 52 overall. The team also prioritized the backup quarterback spot for the first time in years, trading for Ryan Tannehill after watching Mariota battle a laundry list of injuries in 2018. One might use the injuries to excuse his bad play, or alternatively to argue that he'll never manage to stay healthy. Either way, the calls for Tannehill will grow loud if Mariota doesn't make good use of his improved supporting cast early in the season.

After a promising second year, Mariota regressed heavily in his third season. He threw more interceptions than touchdowns, saw his YPA drop by half a yard and failed to top 250 yards passing 10 times in 15 games. His downfield passing reverted to the struggles he had as a rookie, arguably worse. He took fewer than three shots per game beyond 20 yards downfield, completing only 25.6 percent (27th) with a 42.4 passer rating, 32nd among the 34 quarterbacks with at least 20 attempts. Part of the problem was a heavy emphasis on the running game - the Titans ranked sixth in rushing percentage - at the expense of the passing game. That should be corrected this season with the arrival of offensive coordinator Matt LaFleur, the former Rams OC. A big part of LaFleur's offense is play-action, which should suit Mariota well after he led the league in passer rating (122.8) and yards per attempt (11.1) on play-action passes last season. Mariota intends to tweak his mechanics, too, as sloppy footwork led to passes sailing or dying, causing incompletions and interceptions. Health will go a long way. Mariota has not played a full season; last year a hamstring strain held him out Week 5 and limited his mobility the next few games. Delanie Walker, Rishard Matthews and Corey Davis provide upside for the passing game, and this offseason the Titans added pass-catching back Dion Lewis. It's time for Mariota to fulfill his potential.

Mariota's second season ended in Week 16 last year with a fractured right fibula. While he was not yet running full speed at May workouts, he is expected to be ready for training camp. His rookie season ended with a sprained MCL in his knee, and durability looks to be his only issue. After struggling on deep throws as a rookie, Mariota made a big jump in accuracy last year on attempts of more than 20 yards, taking his completion rate from 22.5 percent (33rd) as a rookie to 39.1 percent (15th). His QB rating soared from 50.6 (29th) to 117.4 (4th) on deep throws. Improved line play helped his sacks drop from 38 to 23 despite 66 more dropbacks. A vastly better running game and the addition of WR Rishard Matthews contributed to his growth. Those pieces, and standout TE Delanie Walker, are in place again, and the Titans added speedy 6-3 WR Corey Davis with the fifth overall pick, giving Mariota a playmaker on the outside. Davis could become Mariota's go-to in the red zone, where the QB has thrown 33 TDs without a pick. The 6-4 Mariota is an exceptional athlete with the speed and quickness to make plays with his legs (sixth in QB rushing yards last year), but the Titans could limit his running to avoid exposing him to hits. That's about the only drawback, though, as Mariota looks poised to jump into the top 10 of fantasy QBs.

The second overall pick in the 2015 draft, Mariota found himself under center in Week 1 and stole all the headlines by throwing four TDs before halftime, finishing his debut with a perfect passer rating while only playing three quarters in a rout. It was mostly downhill from there, though, as various injuries limited him to 12 games and unimpressive passing totals. An extremely gifted athlete, Mariota could become the league's most dangerous scrambler not named Cam Newton, and he also has a quick release and excellent footwork, albeit with merely adequate arm strength. That lack of elite arm strength, as well as a lack of elite receivers, led to Mariota posting a poor 58.3 QB rating on passes of 15-plus yards. The question now for 2016 is how much he'll be allowed to do under center. Sacked 38 times —a rate that would have tied Blake Bortles over 16 games as the league's most-sacked QB — Mariota should have better protection after the Titans drafted tackle Jack Conklin eighth overall. The team also traded for DeMarco Murray and drafted Derrick Henry in the second round, and while an improved rushing attack will take significant pressure off Mariota and perhaps keep him healthier, it also signals a shift in offensive philosophy that could limit his pass attempts and fantasy ceiling.

The only knock on Mariota coming out of college — and the biggest reason he was drafted second behind Jameis Winston — is he played in a spread attack at Oregon. Mariota was rarely asked to make multiple reads or throw into tight windows. How long it takes him to adjust to that aspect of quarterbacking is anyone's guess, but he is expected to start Week 1. Mariota is a rare athlete who posted elite marks in drill after drill at the Combine, including a 4.52 40. The 2014 Heisman Trophy winner is the ideal dual-threat QB: both quick and fast, strong-armed, throws well on the run, agile, accurate and intelligent. The Titans said they plan to tailor their offense to fit Mariota's skills. Tennessee's receivers are more steady than explosive, but second-round pick Dorial Green-Beckham has the potential to be a size/speed playmaker right away at 6-5, 237, with a 4.49 40. The 6-4 Justin Hunter provides another big target, and last year's leading receivers, Kendall Wright and Delanie Walker, are reliable, while newcomers Harry Douglas and Hakeem Nicks are savvy veterans who can help.
