The circus rolls on with lots of unhappy campers

Chaos is inscribed in their greenand-white DNA, no matter who is coaching the Jets or supervising their broken-jawed quarterback. These guys know how to write headlines with their hands tied behind their backs — and probably would benefit greatly from that specific physical arrangement.

On just another practice day in steamy, stormy Florham Park, the Jets managed to pull a few more frat-like hijinks on everyone, including themselves:

l Geno Smith showed up for a physical exam after surgery, didn’t bother to stand along the practice sidelines to make a statement or speak with Todd Bowles, and was ordered by club officials to stop throwing footballs outside his house.

l The Jets devolved into two skirmishes during scrimmages — one garden variety, one downright mean — and were ordered by Bowles to run a series of five, round-trip wind sprints across the width of the field as punishment.

l Bowles announced that slot receiver Jeremy Kerley was in a competition for his position with Quincy Enunwa, leaving Kerley somewhat surprised at the declaration – though he surely had an inkling of the situation, after practicing part-time with the second team. Or, as Kerley put it, with considerable understatement, “I signed a contract last year and some crazy stuff happened.”

So yes, this was your basic day at Camp Runamok, even as Bowles, a decent, calm fellow, attempted to impose a sense of decorum and purpose on the pinball franchise.

“Bravado, swagger is fine,” Bowles said. “To get into a fist fight is what you don’t want ... Someone can break a hand on a helmet.”

Or a jaw. About 30 minutes after a brief, mass melee at the 50-yard line, Dalton Freeman and Jason Babin got into a nasty fight that left Freeman on the ground, looking up. That was enough for Bowles to mandate the gassers, though he doubted his players would learn from any of it. Asked if the Jets would continue to get into these intramural battles, despite the punishment and despite what happened to Smith, Bowles admitted that was likely.

“Probably,” Bowles said. “Testosterone. Guys out there a long time. It’s football.”

Smith, of course, is not supposed to be playing football quite yet. A photo of him throwing passes to a friend was enough to earn him a lecture from Jet doctors and officials — who worried that he might injure himself or risk infection.

Bowles also was concerned that Smith might lose too much weight if he is unable to consume solid food. The coach did not get the opportunity to express these thoughts to Smith, who spoke with a few teammates inside the practice facility before heading home.

This had been a wonderful opportunity for Smith to safely stand along the sidelines for a few minutes at the Jets’ practice facility, watch some drills, speak with Bowles, maybe wave to a few of the many Jet fans who showed up to watch the team.

That didn’t happen. Smith’s disappearing act represented just another public relations gaffe by the quarterback.

Meanwhile, Kerley appeared taken aback by what he considered a lack of communication from the staff about his role. Last season under Ryan, the wide receiver caught 38 passes for 409 yards and averaged eight yards

on punt returns.

Asked if he would have liked to know about this competition with Enunwa, Kerley responded, “It would be nice.”

“I signed my contract with a different organization,” he said, about the regime change from Rex Ryan and John Idzik to Bowles and Mike Maccagnan. B“I definitely feel like I proved myself.” owles did not seem overly concerned with any of these goings-on. Unlike other teams that practice in the cooler mornings, he purposely has scheduled workouts for the hottest time of day, early afternoon. A couple of weeks earlier, Bowles complained the weather was not steamy enough. For the first hour of practice on Sunday, before some clouds intervened, the temperature was 93 degrees in Florham Park and the sun baked everyone.

“It’s getting there,” Bowles said, when asked if this was hot enough for him. “Tempers were flaring, so I guess it was hot.”

Or maybe it was just the Jets.
