There is an interesting story out there here in the LA TImes ...(if that link is dead try this one) Brandon Ting, a backup player on the USC football team and his twin brother abruptly left the team last week. Seems one tested positive for 'roids.
It should also be noted that the twins sport above a 3.8 GPA in pre-med, which is a GPA on steroids.
Their father is Dr. Ting, Barry Bonds orthopedist. Dr. Ting has been implicated in several disciplinary actions. The most recent involved poor records in the delivery of dangerous drugs to friends and athletes.
