Well I'm kind of at a quandry with this one. I saw the Miracle on Ice, but I was a 10 year old kid with no interest in hockey. It wasn't until many years later I was able to appreciate the significance of that win and how it's hands down the biggest upset in the history of sports. Then there's Italy's upaet of France in the 06 WC, the i famous Zidane head butt game. This time I was fully aware of what I was watching but with no interest in who won aside from the natural inclination to pull for the underdog. But as for a personal favorite with historical significance and huge fan investment, it has to be Gonzo's walk off single off Mariano Rivera to give my underdog Dbacks a WS ring over the heavily favored and hated Yankees
