I think there is an obscure NCAA rule that allowed borderline academic cases like Pierre to enroll in school despite not being fully qualified, BUT to have to focus on school for a full academic year and not play a sport.
So, the guy in the directory could be the football team's Pierre, enrolled in school under that rule. And if he garners at least a 2.0 GPA, then he'd be qualified to join the football team in summer camp.
Or, the guy in the directory might just have the same name by coincidence. Nobody knows at this point.
