Marcus Mariota might be out as the starting quarterback in Tennessee, while the Tampa Bay Buccaneers might have to decide how many more interceptions they can afford from Jameis Winston.

• Jameis Winston threw five interceptions in the Buccaneers' loss to the Panthers on Sunday
• Bucs coach Bruce Arians said Winston would remain the starter for the Bucs
• Tampa Bay is 2-4 to start this season and has no playoff appearances since drafting Winston in 2015

For the top two picks in the 2015 draft, the future might not be so bright.

Mariota was pulled in the third quarter of a 16-0 loss to Denver with 63 yards passing, a 9.5 rating, two interceptions and three sacks. Winston made it to the finish of Tampa’s 37-26 loss to Carolina in London, but with a career-worst five interceptions — and an oh-by-the-way fumble for a sixth giveaway.

Winston has an NFL-worst 86 giveaways since entering the league and five games with at least four turnovers while no other player has more than two during that span.

“Throw the damn ball away,” coach Bruce Arians said. “He has a habit of trying to be Superman. That’s been a problem in the past. The fumbles haven’t occurred this year until today. But again, trying to make something out of nothing. It’s just a matter of knowing when to quit on a play.”

Mariota has a better record (29-32 compared to 23-37) and a slightly better ratio of touchdowns to interceptions, while both have similarly mediocre passer ratings in the high 80s.

The problem for Mariota is that Titans are near the bottom in points and total yards and have been shut out twice since the start of 2018. Ryan Tannehill, a former starter in Miami, replaced Mariota and was 13 of 16 for 144 yards and one interception. He was sacked four times.

“We’re not pulling our weight as an offense,” Mariota said. “We have to find a way to improve and change that because our defense is playing lights out.”

Titans coach Mike Vrabel didn’t want to discuss who would be the starter going forward.

Between Mariota and Winston, Mariota has the only playoff appearance. He won a wild-card game during the 2017 season. Neither has signed a second contract, which means both are in the fifth and final years of their rookie deals.

So both teams have decisions to make in the offseason, if not sooner.

“Sometimes I do want to do great things,” Winston said. “But you can do great things but protect the team at the same time.”
