High school coach suspended for prop bets on students

What started as a bit of ‘harmless fun’, has turned into a headline about trust, responsibility, and where gambling fits into American sports culture. A well-regarded Pennsylvania high school coach has been suspended after running prop bets with students, and the fallout has gone far beyond the school gym.

A coach in the spotlight

David Zimmerman, a celebrated soccer coach at Conestoga High School, was removed from his duties after he was discovered to be organising prop bets around basketball games. The bets, as little as $10 a piece, weren’t placed through operators, but rather scribbled on small slips of paper.

No one got rich, no one opened an online gambling account, but the optics were enough. An adult in a position of authority introducing gambling to underage students was judged serious enough for immediate suspension. According to The Philadelphia Inquirer, the school has since rewritten its code of conduct to explicitly ban gambling of any kind on campus.

The bigger picture: prop bets under fire

Zimmerman’s suspension comes at a moment when prop bets are already drawing national scrutiny. The NCAA has warned about gamblers targeting athletes, with president Charlie Baker telling ESPN earlier this year: “Props create real threats to players’ well-being and the integrity of games. Removing them from college sports is common sense.”

In March 2024, a bipartisan group of U.S. senators introduced a bill seeking to ban prop bets on college athletes nationwide. Professional leagues may be happy to cash in on sports betting, but for schools and colleges the ground is shakier: younger athletes, less oversight, and a bigger risk of harm.

That backdrop explains why a modest high school betting pool has been treated as more than a one-off lapse.

Addiction, influence, and authority

The incident has also touched a nerve among addiction experts. Harry Levant, director of gambling policy at Northeastern University’s Public Health Advocacy Institute, told The Inquirer: “If someone in a position of respect and authority is introducing kids to an addictive substance and somehow normalising that or minimising its significance… Neither would be acceptable to me.”

Research suggests the concern is real. A 2023 report from the National Council on Problem Gambling estimated that up to 60% of teenagers had gambled informally before 18. With betting apps saturating sports ads and social media, exposure is higher than ever.

Psychologists warn that betting on the “minutiae” of games (like who scores the first basket) creates fast, repetitive play patterns more addictive than traditional gambling. When those habits are endorsed, even playfully by a trusted coach, it’s clear why it’s considered irresponsible.

A cautionary tale

For Conestoga High, officials stressed that the betting wasn’t widespread, but a coach organising pools with students was enough to trigger a firm response. The school has since tightened its code of conduct, leaving little doubt on where it stands.

Likely, Zimmerman’s actions weren’t inherently malicious; however, this episode has landed in the midst of a much wider conversation already taking place in U.S. sports, one about prop bets, regulation, and how gambling fits into environments where younger people are directly involved, and therefore exposed.
