Pete Carroll plays joke on his USC football team

USC head football coach is a prankster. He pulled a April Fools joke on defensive end Everson Griffen and this past Sunday in camp he decided to play one on his whole team. Carroll says that defensive end Kyle Moore was caught by police in an internet piracy ring, but in the end tells his team in lieu of practice the team will go bowling instead. The players seem to have enjoyed it. What's with coach picking on the d-ends for?
