NASHVILLE Parris Campbell Jersey , Tenn. (AP) — Going into the final year of his rookie contract, Marcus Mariota hasn’t changed anything about how he prepares for this season.That includes no talk of holding out or public demands for a new contract. The Titans quarterback and 2014 Heisman Trophy winner prefers to show up and work hard during the voluntary offseason program to be the best he can be.“Let it ride,” Mariota said Tuesday. “I mean no matter what still I get to come out here. I get to play a game that I love and I’m going to make the most of it.”Mariota’s injury history is the reason why the Titans have yet to sign the quarterback to an extension after picking up his option for 2019 at $20.9 million. He has missed at least one game a season and eight combined through his first four years, and he is coming off a season where he threw for a career-worst 11 touchdowns with eight interceptions.A revolving cast of coaches hasn’t helped.Coach Mike Vrabel is Mariota’s third head coach since being drafted No. 2 overall in 2015, and Arthur Smith is his fourth offensive coordinator and fifth play-caller. Vrabel promoted Smith from coaching tight ends to make the transition as smooth as possible — the only offensive change after coordinator Matt LaFleur was hired as Green Bay’s new head coach.“I hope that there’s a lot of carry-over,” Vrabel said of his offense.Both Mariota and the Titans have plenty of room for improvement on offense. Thanks to a dominant December by Derrick Henry running the ball, Tennessee ranked seventh in that category in 2018. They ranked 29th in passing offense, managing a mere 189.5 yards per game after losing Mariota’s top target — three-time Pro Bowl tight end Delanie Walker — in the opener.Mariota threw for more than 300 yards only once in an overtime win over Philadelphia, and the Titans had three games where they didn’t reach 100 yards passing. Mariota missed three starts, including the regular-season finale when a victory would’ve earned a second straight playoff berth.The Titans upgraded Mariota’s backup, trading for Ryan Tannehill in March. They also signed wide receiver Adam Humphries and new left guard Rodger Saffold to improve the offensive line while drafting another receiver in A.J. Brown to give both Mariota and the offense a boost.“I feel like as a team we’ve made some good choices, and hopefully they can bring something dynamic to the offense,” Walker said.Mariota wouldn’t bite when asked how little he needs Tannehill to play this season.“No matter what, I know he’ll be prepared if it comes to that and he’ll make the most of his opportunity,” Mariota said.The Titans made clear when they traded for Tannehill that Mariota remains their starter, though that hasn’t stopped speculation that Tannehill was brought in to push Mariota.“His job is not in jeopardy,” Vrabel said of Mariota.The quarterback and Smith know each other well having spent the past four seasons together through all the different schemes. Mariota said Smith also makes it easy for players to talk to him about what they like and don’t like.Mariota, who sat out the final game last season because of nerve issues affecting his throwing arm, looked fine on the second day of the Titans’ organized team activities in the final phase of the offseason program. Mariota threw short Bobby Okereke Jersey , mid-range and long passes.The quarterback said he wishes those health issues hadn’t happened, especially at the end of the season. He’s working to be healthier, having gained a few extra pounds to help. But he’s not going to worry about the concerns others have about his durability.“Other people’s opinions don’t matter to me,” Mariota said. “I just got to be the best I can be for this team.”NOTES: Walker, who broke his right ankle in the 2018 season opener, took part in practice even as he was limited to four snaps in a team drill at a jog. Walker said he felt good. “As a team, we talked about it, and this is the plan they got for me,” Walker said. “So I’m happy with the plan. Just taking steps pretty much.” DETROIT (AP) — A season of ups and downs for the Minnesota Vikings comes down to this: beat Detroit and Chicago and they’re in the playoffs.First up are the banged-up Lions, who have already been eliminated from postseason contention, but with so much at stake, the Vikings can’t afford to look too far ahead.“We know what we’ve got to do at this point. We know how we’ve got to play,” running back Dalvin Cook said. “There’s little time for error right now. We just have to go out there and play clean football and win football games.”Article continues below ...Minnesota won just one of its first four games this season, and the Vikings haven’t come close to matching last year’s 13-3 record. There will be no division title — Chicago already clinched that — but if the season ended now, the Vikings would be in the playoffs, so they still have all sorts of opportunities ahead of them.First, they’ll try to take care of business in Detroit.While Minnesota (7-6-1) has been underwhelming this season, the Lions (5-9) never really looked like contenders. They dropped their first two games, traded receiver Golden Tate and have now lost a handful of key players to injuries. Rookie running back Kerryon Johnson Khari Willis Jersey , defensive end Ziggy Ansah and wide receiver Marvin Jones are all on injured reserve.Detroit hasn’t scored more than 22 points in any of its last eight games.“Obviously the playoffs are, that’s the goal and that’s what you’re shooting for every single week,” said Matt Patricia, the Lions’ first-year coach. “The thing that’s different, I think, is that every week you don’t walk into the room and talk about playoffs. You just kind of walk in and talk about the game that week. … The fact is, we still have to go play a really good Minnesota team this weekend that’s coming off a huge win.”The Vikings beat Miami 41-17 last weekend.A few more things to watch when the Lions host the Vikings:STACKS OF SACKSThe Vikings set a franchise record with 10 sacks in a win over the Lions earlier this season , and they’re coming off a nine-sack performance against Miami. They lead the league with 47 sacks.“You know that they’re going to come out there, they’re game-planning against what we’ve done the first time,” said defensive end Danielle Hunter, who’s tied for second in the NFL with a career-high 14½ sacks. “We’d expect to see more max protection, them running the ball and all that. Stuff like that.”Lions quarterback Matthew Stafford has been sacked five times or more in 16 games of his 10-year career, and seven of those were against the Vikings.STREAKStafford missed 19 games in his first two seasons while plagued by injuries. He’s started every game since, a streak of 126, not including the playoffs.“It means a lot. Well documented, first two years, (I) missed a bunch and I wanted to prove to my teammates, this organization, myself Josh Allen Jersey , everybody, that I could be out there for extended periods of time,” Stafford said.Stafford has been limited in practice recently because of back issues, but he pushed back against the idea he should sit now, with the playoffs out of reach.“I spend all offseason and all season working hard to play in games with these teammates and for this organization,” he said. “(I) take no games for granted and go out there and play whenever I feel like I can.”READY TO RETURNThe first of five career punt returns for touchdowns for the Vikings by Marcus Sherels came on Sept. 30, 2012, at Detroit. Last week against the Dolphins, Sherels had a 70-yard return and totaled 116 yards on five returns.“We kind of challenged him a little bit this last week at being more aggressive,” coach Mike Zimmer said.Detroit has activated returner Jamal Agnew off IR. He was an All-Pro last season.ANOTHER OPTIONWith opponents frequently sending double teams at Adam Thielen and Stefon Diggs, the Vikings have needed other pass catchers to step up for quarterback Kirk Cousins.Aldrick Robinson, who was signed as a free agent two weeks into the season, has shown some potential. His 40-yard touchdown reception against the Dolphins gave him five scores in 10 games. He’s reached the end zone on nearly 30 percent of his 17 receptions.MARK OF FAILUREFrom 2001-12, the Lions had double-digit losses 10 times in 12 seasons. It hasn’t happened since that 2012 season, but Detroit needs to win its final two games to avoid it this year.
