Three-time Olympian Blaine Wilson's comeback ended after two events Thursday when he withdrew from the nationals and announced his retirement. "I got through floor exercise and I said, 'I’m just tired,'" Wilson, 33, said he told coach Miles Avery. (Tired of what -- being so damn hot?) He added, "It's been a good run ... It was a good idea for me to walk away." Between Blaine and Alexei Nemov, there was actually a time when watching the Olympics was fun. I hope his retirement is everything he hopes it will be. Last time he tried things didn't go so well.
