Look at Golota
Andrew Golota the boxer? One of my great disappointments ever in sport was when he folded like a deck chair in the first round against Lennox Lewis in 1997. I was sure he had the talent and toughness to defeat the pompous Jamaican-Canadian-Brit (depending on what day it was) Lewis. I stayed up to about 3 or 4am British time to watch it and was fuming at Golota's meltdown. It was a complete embarrassment.
