FRESNO, California – An assistant football coach at a U.S. high school led his team to a string of victories by improperly recruiting more than a dozen players from American Samoa and offering them housing, according to an investigation by local sports authorities.

The six-month probe alleges a Samoa-based relative of the coach began meeting with the students’ parents as early as 2004, and persuaded them to send their sons from the remote South Pacific island to Stockton, a city 50 miles south of Sacramento. Once there, the coach is accused of housing the students at his home, with his brother or with other coaches.

Fourteen students and their families flew to California on tickets purchased by the coach’s mother, and were put up in motels for a week paid for by Franklin High School personnel, authorities said. The coaches helped the parents get fake utility bills to establish their sons’ residency, and the Yellowjackets gained a new set of recruits to advance their standing within the league, officials said.

“Who knows where they would have been if they hadn’t had those kids,” said Pete Saco, a regional commissioner of the California Interscholastic Federation, the governing body for high school sports in the state. “Our goal is that everybody has to play by the rules. That’s the essence of what high sports is all about.”

While not criminal, athletic recruiting at the high school level is not permitted by high school sports governing bodies in United States, along with exercising “undue influence” to coerce young students to switch schools, sports authorities said.

Still, administrators in the Stockton Unified School District questioned the report’s focus on students from one ethnic group.

Dozens of students of Samoan descent play on other teams in the Central Valley area, and all three Samoan students enrolled at Franklin High School are in compliance with the rules, said Superintendent Jack McLaughlin.

“We viewed this in the beginning as kind of an attack on a culture,” McLaughlin said.
