Dennis Rodman
It’s probably more accurate to say that Rodman’s partying destroyed his post-career than his actual career. He was one of the best defenders and rebounders ever when he starred for the Pistons and the Bulls. But he always enjoyed letting his hair down as star teammate Michael Jordan would attest. Rodman once went partying in Las Vegas with Carmen Electra. It took Jordan’s intervention to drag him back to action.

After Rodman retired from the NBA, he continued to be a wild party animal. However, his behavior became increasingly erratic and he made strange decisions. These days, young NBA fans know him as the weirdo who hangs out with North Korean dictator Kim Jong Un. Unfortunately, they don’t know how good he was during his heyday (via TalkSport).
