"I want to protect the improvements we've made," he said.
When Singleton canceled sports, speculation ran wild about the repercussions his decision would have on enrollment, attendance and student engagement.
Yes, a few students left — enrollment is down 15 students from last year — but the district did not see the mass exodus that was predicted. Attendance is better this year, not worse, and more students are passing their classes.
"We're actually learning this year," senior Javier Moralez said.
School is calm — there hasn't been a single fight this year — and, when the high school held its fall open house, 155 people showed up. Last year, six came.
The district has made drastic progress toward accomplishing the mandates the state set in December for Premont ISD to remain open, Singleton said.
Just thinking about it takes him aback.
"How is it possible that we could accomplish all this from January?" he said.
Singleton worries that bringing back football could implode those achievements. The sport consumes vast amounts of student and teacher time in late night practices, weekend film review and travel to away games. That's time that could be better spent on academics, he said.
Then there's cost.
The district saved about $100,000 by canceling fall sports. Not only would Premont ISD have to foot that expense next season, it must also find a way to pay for necessary improvements to the aging and dilapidated Jimmy Livingston Football Stadium, where the only modern features are the shiny, locked padlocks dangling from the sagging and rusted chain link fence.
The rickety bleachers on the visitor's side are condemned. The scoreboard no longer lights up properly, and the bathrooms are subpar.
Still, the football field has remained relatively well-groomed, rescued from the encroaching carpet of grass burrs by Pee Wee football.
This season, instead of spending Friday nights watching the Premont Cowboys from the football stands, Pee Wee football coaches spend it on the field, edging and clipping the grass into a series of recognizable yard lines so they can play there Saturday morning.
"No football, just this," said Rick Ortiz, coach of the town's Pee Wee team.
Ortiz, who played defensive tackle for the Premont Cowboys in the late 1980s, wasn't happy when the district canceled sports. He thought the decision unfairly punished students and forced some to move elsewhere.
The good news is Premont's future can only get brighter, he said.
"We hit rock bottom already," Ortiz said.
Of all the sacrifices and tough choices that Premont has faced in its struggle to survive, the decision to give up sports likely caused the biggest ripple effect.
Friday nights typically meant a packed parking lot at the Oasis Restaurant on U.S. Highway 281, a staple for the postgame meal. Now, school buses drive past the restaurant on their way to other games.
To stay afloat, the Oasis has gone mobile.
"Let's put it this way: Thank god for the Eagle Ford Shale," restaurant manager Rosie Pena said of the booming oil and gas formation.
The restaurant operates two food trucks that travel as far as Shiner to feed the oil field workers. That business along with hunting season will help keep the restaurant in business, Pena said.
Still, Pena doesn't fault Singleton, a lunch regular at the Oasis, for canceling sports. She understood the necessity for the decision and the district's dire situation.
"I think it was a good idea," she said. "For us to keep our school, we can do without sports for a little while."
