I had mine during the finals game for the NBA playoffs 2016. GSW against CAVS, from the very beginning of the best of 7 series. I already knew how better Kyrie is than Curry. Infact comparing both's statistics, Curry is quite outnumbered by Kyrie on the Fields Goals stats. Basing from my own point of view i had a strong feeling that kyrie and the CAVS team can handle Both Clay's and Steph's momentum once it has unleashed. They knew how to prevent these guys from scoring more in order for them to win. I was very confident that time that it will be the Cavaliers that will win.
But unfortunately, the worst mistake on gambling i've done was to put a doubt on Lebron and instead placed my whole $100 in favor of GSW to win the whole series. The moment CAVS won the game 7, I was totally pissed and regretful of the decision i've made. I should have relied on my feelings rather than putting a doubt on Lebron's ability to handle 4 quarters Scenario. I was bit right on the doubt I had, But it was Kyrie Irving that made everything for cavs in order to win a historic championship they are enjoying now.
