One of the best running backs in USC history is not welcome at the team’s practices. That’s because the person in question is convicted felon and accused murder, O.J. Simpson. Simpson was granted parole last week after serving nine years in prison for armed robbery and kidnapping. He is set to be released on Oct. 1. In light of Simpson’s parole, LA Times reporter Dylan Hernandez decided to ask USC head football coach Clay Helton Thursday whether the “Juice” would be allowed to attend practice if he asked to visit, as many former players do.
