One of the possible 'penalties' is suspension for some period of time from U.S. "teams"- which could run the gamut from Pan Am Games through World Cup, World Champs, and even Olympic Games, depending on how long the penalty is. Such a penalty would not prevent him from 'earning a living' in individual tour stops or invitational meets. And it would also focus the penalty to a narrow, specific type of competition where the transgression occurred to begin with. Namely doing something- rabbiting for an 'opponent'- which is perfectly okay in invitational meets, but is considered a conflict of interest in team-scored events and a violation of obligatory responsibilities when accepting a team berth. You don't do anything to intentionally help an opposing team score points.
But that's just one penalty possibility- we'll have to see what transpires. RT
