CLEVELAND, Ohio -- Jets coach Todd Bowles was in no mood to attribute his team's collapse in the 21-17 loss to the Browns to a momentum shift when Baker Mayfield entered the game 1:42 left in the half.

Mayfield came in for a concussed Tyrod Taylor to bust open beer coolers all over town and snap a 19-game winless streak that spanned 634 days.

"No, I felt the same as soon as we committed two penalties before halftime, and we gave them life with the penalties,'' he said. "I don't think it had to do with the quarterback."

Despite Mayfield storming back with 21 points and 201 yards in a little over a half, Bowles pinned this loss -- which dropped the Jets to 1-2 and improved the Browns to 1-1-1 -- on penalties.

"It's inexcusable on a few penalties we had,'' Bowles said. "We gave them life before the half. We had two of them. We had one there on the two-point conversion that we had no business having, and we let them back in the game with some key penalties and it cost us. We lost our composure. I told the team that we lost our composure and we should be pissed off up until we play the game next weekend.''

Bowles didn't think Mayfield's quicker pace was to blame for his team's collapse.

"I don't think it was a hurry-up at all,'' he said. "I thought guys got gassed in the second half. They were the same plays. I give the guy credit - he played well. We didn't do the things in the second half that we did in the first half."

He said it's not that the Jets weren't prepared for Mayfield.

"They were the same plays,'' he said. "We knew what the quarterbacks were. We knew one ran more than the other. He just did a good job and we didn't."

One of those at the end of the first half was an unsportsmanlike conduct call for running back Isaiah Crowell wiping his rear end with the ball and then firing it into the stands.

"That was inexcusable,'' he said. "We addressed it and it will never happen again."

He blamed the loss on himself.

"I'm taking the whole ball game. This whole ball game falls on me."

As for giving up the 2-point conversion on the Philly Special pass from Jarvis Landry to Mayfield that tied the game at 14, "it was more the coverage than the play. We were on different pages and the coverage was blown."

Some of the Jets echoed his sentiments, attributing the loss to mistakes rather than Mayfield electrifying The Factory of Sadness.

"He just made a couple throws,'' said linebacker Darron Lee. "Looking back on it, from what I recall, I am just really frustrated in the fourth [quarter] with all the penalties."

Others, such as Jets quarterback Sam Darnold (15-of-31, 169 yards, 0 TDs, 2 INTs, 38.2 rating) acknowledged the spark Mayfield provided.

"I know Baker is a great player,'' he said. "He's done some great things at Oklahoma and he continued to do great things tonight. I felt the crowd rallied pretty well around him. At the same time, I have to continue to do my job and keep the offense rolling. I'm not worried about that."
