Coach Todd Bowles was not pleased with all of the penalty flags his team drew in Friday night’s preseason win over the Falcons.

The Jets ended up with 17 penalties, 10 in the first half. Darrelle Revis picked up a holding call in the end zone and the secondary was whistled for three straight penalties at one point. There were personal fouls and holding calls. Tight end Kellen Davis had three penalties by himself.

“You ain’t going to win no ballgames having 17 penalties,” Bowles said. “Effort was great, penalties were terrible. That was way more than imagined. We got better in some areas. We got worse there. We’ve got to clean that up.”

The players said Bowles’ main message after the game was about cleaning up the penalties.

“We can’t beat ourselves,” guard Willie Colon said.

Bowles stressed tackling after a poor performance against the Lions last week. He saw improvement in that area Friday night. Now, he hopes the same thing happens with the flags.

“Hopefully we learn from penalties this week,” Bowles said. “We’ve got to get better every week. We’ve got to progress next week. Hopefully, the penalties go down. We’re going to work our asses off on it and we’ll go from there.”

Rookie quarterback Bryce Petty played much better in his second outing. Petty went 12-for-19 for 168 yards and a touchdown after looking shaky in his debut against the Lions.

“He was a little more poised,” Bowles said. “That’s the progress we’re trying to get with him, get better every week, a little bit better every week. He got better from last week to this week. Hopefully, he’ll keep moving forward.”

Petty said he was not as nervous this time out.

“I think last week I had no idea what to expect as far as the game goes, as far as myself emotionally how it would roll,” Petty said. “I felt like coming into this week I would have a better understanding of how things went down and how things work. I felt a lot more comfortable out there.”

The Jets had three players leave the game with concussions: WR Jeremy Kerley, RB Daryl Richardson and safety Durrell Eskridge. WR Shaq Evans left the game with a sprained back after a vicious collision with Kerley and a Falcons tackler. OT Ben Ijalana (knee) and CB DeShaun Phillips (ribs) also exited the game.

DE Stephen Bowen started in place of Muhammad Wilkerson (hamstring). Safety Jaiquawn Jarrett started in place of Calvin Pryor (death in the family).

Here’s how the Jets fared in some key areas Friday night:

Punchless defense

The starting defense looked terrible during its one true drive against the Falcons’ first-team offense. The Jets gave up 85 yards and a touchdown on six plays. The big play was a 60-yard pass from Matt Ryan to fullback Collin Mooney. Thumbs down

Flag day

The Jets looked terribly undisciplined. They picked up 10 penalties in the first half alone, 17 for the game. Tight end Kellen Davis was the main culprit, with three penalties. Thumbs down

The Big Cat roars

Rookie defensive lineman Leonard Williams had a monster game. Williams got the Jets on the scoreboard with a safety in the second quarter. It was the first of his two sacks. Thumbs up
