The latest black eye for college sports belongs to the NCAA.

In an embarrassing blow to its watchdog image, the NCAA said Wednesday its enforcement staff had botched the high-profile investigation of the University of Miami by improperly conducting at least two depositions while working with an attorney for disgraced booster Nevin Shapiro. Miami has been under investigation since the convicted Ponzi scheme mastermind said he had provided improper benefits to Hurricanes recruits.
