18. Darren Sharper
In 2014, Darren Sharper was arrested on two counts of sexual assault. It was shocking at the time as during his playing career he was one of the NFL’s best safeties. He played for the Green Bay Packers, New Orleans Saints and Minnesota Vikings. He’s all got the joint-record for most defensive touchdowns of all time.
This is where it gets seriously dark. After his playing career ended, allegations started to come out about Sharper’s disturbing activities. It was discovered he had been crossing multiple states where he was drugging and raping women. Now he’s serving a 20-year prison sentence. A depraved individual.
