Cleveland Browns quarterback Baker Mayfield (6) makes a call during last week's loss to Denver. Mayfield was much calmer while meeting with the media this week despite the Browns' four-game losing streak.

BEREA, Ohio — Baker Mayfield completed his media session without incident and even sported the same mustache he woke up wearing.

At this point, those two things are considered progress for the Browns’ struggling second-year quarterback.

With Cleveland mired in a four-game losing streak inside a season unexpectedly unraveling, Mayfield projected a buttoned-down image on Wednesday as the Browns (2-6) prepared to host the Buffalo Bills (6-2) on Sunday.

Following practice, Mayfield spoke deliberately and objectively while discussing the team’s struggles, his own performance and his hopes of salvaging the season.

No swagger. No sarcasm. Humility.

“We have to stay the course,” he said.

It was a contrast to last week, when a perturbed Mayfield objected to a question and stomped away from his weekly news conference in Cleveland’s locker room. That was followed by a strange sequence in Denver when he curiously shaved before and after a 24-19 loss to the Broncos.

Mayfield started last Sunday with a beard, wore a Fu Manchu mustache during the game and then showed up to his postgame press conference with only a mustache.

On Wednesday, he explained his grooming habits.

“The original thought for me, do handlebars,” said Mayfield, who has maintained the postgame look, which went viral on social media. “I was undefeated before Sunday with the handlebar mustache. So I shaved it off because I didn’t deserve it.”

It’s been that kind of season for Mayfield.

Nothing is going his — or the Browns’ — way.

Although he didn’t throw an interception on Sunday, Mayfield remains tied for the league lead with 12 picks. He’s also last among qualifying QBs in completion percentage (58.7) and touchdown-to-interception rate (0.58).

His frustration has been building, and he acknowledged being exasperated in a Twitter posting following his touchy exchange last week with a reporter, who had asked him about a lack of urgency during the previous week’s loss at New England.

The Browns outgained the Broncos, controlled time of possession, cut down on penalties, didn’t commit a turnover and still lost.

Mayfield said there’s only one way to straighten out the season.

“Stay the course,” he said. “I think no matter what’s going on, we’ve made strides in certain areas that we needed to, but now we just have to make the plays when they’re there.”
