A Kentucky high school football coach threatened to run players until someone quit the team, but did not violate any high school athletic rules when a player collapsed during practice, a school system report concluded Wednesday.

The Jefferson County Public Schools report also said there was evidence that 15-year-old Pleasure Ridge Park lineman Max Gilpin may have been ill with a headache and congestion before the practice.

A lawyer for the player's mother, who has filed a lawsuit over the death, however, disputed the doctor's findings.

The report comes about 10 months after Gilpin collapsed while running at the end of a preseason practice. Gilpin died three days later of septic shock, multiple organ failure and heat stroke.

Former Pleasure Ridge Park coach David Jason Stinson has been charged with reckless homicide in a rare criminal case involving a player's heat death. He has pleaded not guilty and a trial is set to begin Aug. 23

The 300-plus page report states that Stinson, upset that some players had been goofing off during practice, told the team they would run a series of sprints, known as "gassers," until someone quit the team. The report said such a workout isn't against any rules or policies.

Jefferson County Schools Superintendent Sheldon Berman said he was "extremely troubled" by what Stinson told the players.

"Such motivational tools are not acceptable," Berman said.

Berman said the school district will train coaches to use positive motivation with athletes.

The report also said an independent physician hired by the district to review the case, Dr. Daniel Rusyniak, found that there was evidence Gilpin was ill prior to the Aug. 20 practice. The doctor concluded that an illness would have made Max more susceptible to heat stroke, but with no autopsy, the cause of his sepsis was more difficult to confirm. Rusyniak, a specialist in emergency medicine at Indiana University, reviewed Gilpin's medical records, but did not examine him.

The report also notes Gilpin had been taking the dietary supplement creatine, as well Adderall, an amphetamine prescribed to treat Attention Deficit Hyperactivity Disorder.

The report said the coaches were not aware Gilpin had taken creatine, but also found there wasn't enough information to say whether creatine or Adderall contributed to Gilpin's death.

Side effects for creatine, an over-the-counter supplement, are listed by the National Institute of Health as cramps or muscle breakdown, heat intolerance and electrolyte imbalances. Gilpin's mother has said previously her son had taken creatine but stopped before preseason practices.

Todd Thompson, an attorney for Gilpin's mother, Michele Crockett, said the report's conclusions were not a surprise because the school system has from the beginning sought to exonerate themselves and the coaches in the teen's death.

"I didn't expect them to do anything but blame the child for his own death," Thompson said.

Thompson said Rusyniak's analysis of Gilpin's health is off the mark and a pre-season physical declared the teenager in good health.

Steve Tedder, a spokesman for Jefferson County Commonwealth Attorney David Stengel, said the report was evidence in the criminal case and declined comment. Stinson's attorney also declined comment.

The report laid out a timeline of the practice on a day where the temperature on the field reached the low 90s as measured by the coach — but not above 95, which would have kicked in special hot weather regulations. The report, compiled by the school system's security division that includes former Louisville police officers, noted that players had 4-5 water breaks, including one just before the sprints. The report also states players who showed signs of distress were excused from running.

In the criminal case, prosecutors claim Stinson denied players water during practice. Parents on an adjacent soccer field have said they heard football players being denied water.

Berman said all the evidence points away from dehydration causing Gilpin's death.

"The players felt pretty comfortable getting water when they needed it," Berman said. "The only situation where they were denied water was at the team meeting and that did not involve Max."

School system investigators did not interview Stinson or Gilpin's parents. Berman said Stinson declined to make a statement, citing the criminal case, but was shown the report earlier in the week. Berman said Gilpin's parents declined to be interviewed. The report relied on statements Stinson made to police and responses by Gilpin's parents filed in their lawsuit.

Gilpin's parents have sued Stinson, five assistant coaches and school administrators in a case set for trial in January.

Louisville police took statements from Stinson, 89 football players, nine coaches and 25 other witnesses, including parents at a soccer game on an adjacent field. The school system's report includes much of the same information.

Stinson is still employed in a non-teaching position. He will remain reassigned pending the outcome of his criminal trial. Berman said if he's cleared, he will be eligible to apply for a coaching job again. Officials at Pleasure Ridge Park High School are in the process of hiring a new coach for next season, Berman said.
