CYCLE PREMIERE: This is the 26th time around the block for this prime-time ABC skating competition. And this time, it’s an all-athletes edition, heavy on U.S. gold medalists from the most recent Winter Games. But it also has some less recent, still famous athletes hitting the dance floor – including Kareem Abdul-Jabbar, Johnny Damon, and one of the most infamous Olympic athletes of all time, Tonya Harding.
