Jets offensive coordinator Frank Reich explained on Thursday the reasoning behind several of the questionable decisions that were made on offense that led to the Jets’ 20-17 overtime loss to the Packers on Sunday.

On the sequence at midfield late in regulation with the score tied at 17-17 when Reich opted to run running back Braelon Allen out of the shotgun on fourth-and-1, Reich defended the call.

There was criticism, considering Allen is a 6-1, 235-pound bruiser, that running him from an under-center snap instead of having him start from so deep in the backfield would have been a better play.

Allen was stopped by Packers defensive lineman Lukas Van Ness for no gain, giving Green Bay the ball in great field position with the chance to win the game. The Jets defense held, but they lost in OT a short time later.

Reich’s defense of the call was analytics, as he arrived on Thursday in his weekly meeting with reporters armed with statistical data.

“As a play caller in those situations, everything is always on the table — under center, shotgun, pass, run,’’ Reich said. “I’m always going to call what I think is the best play in the moment, and that’s what I did.

“When it doesn’t work out, sure, you’re upset, you think maybe you should’ve called something else, but you have to live with the results. I’m comfortable and confident in the calls we made.’’

Reich then, “for context,’’ recited a five-year study, excluding quarterback sneaks, that shotgun runs on fourth-and-1 convert at about 71 percent compared to 67 percent under center.

“The gun run is actually better, in part because the threat of a pass keeps the defense from getting too tight,’’ Reich said. “We also had a five-year study showing pass conversion at 57-percent versus 71-percent on the ground. Trust me, we’re going to throw it on fourth-and-1 sometimes too, maybe this week, maybe not.

“But unless you’re one of the few truly elite quarterback-sneak teams, the analytics say a shotgun direct run is the best-percentage call. That’s what we had the most conviction in. We didn’t convert it, so you live with it.’’

Reich spoke with less conviction about the job he did at the end of the first half, when the Jets had the ball with four minutes remaining and proceeded to bumble around on a drive that led to nowhere.

They had no timeouts, because they’d burned two on personnel issues earlier in the half and lost an officiating challenge on a fumble recovery.

The drive began at their own 10-yard line with four minutes remaining and stalled out before midfield as the clock ran out.

“I’ve got to do a better job,’’ Reich said of that circumstances. “Coach (head coach Aaron Glenn) was very clear communicating what he wanted during the game. We were trying to burn some clock, ended up in third-and-two, called a run. We had called two shot plays down the field before that. They covered both, so Geno [Smith] checked it down correctly both times.

“We also called a play with the potential for a big 20-yard gain, they brought a blitz, and Geno correctly checked to a wide receiver screen that picked up eight or nine yards. Then the drive ended. Small sample size, but I’ve got to be better in those situations.’

Reich preached moving forward to this Sunday’s game against the Lions in Detroit from what occurred against the Packers.

“Moving on to Detroit, one of the things I appreciate about our players, this offensive unit, and our coaching staff is the culture of just continuing to fight to get better, with a “Week one, zero” mentality.

“We talked about this before the season started. Once a game is over, win or lose, it’s behind us, and we move on and get better. I think the guys have embraced that. The mood and mindset in (Wednesday’s) practice was very strong.’’
