This is a list from what I saw during my lifetime (obviously)

5. Seeing wlad getting KO'd by Sanders. I didn't like wlad and never thought much of him but he was seen as the next big thing so I was sooooo happy to see him get KO'd. Then losing to Brewster was hilarious too.
4. Watching the first castillo-corrales fight. I wasn't really invested in either fighter but it was so exciting the whole time and then the ending made it epic.
3. Freitas knocking out barrios in the 12th round. I was a big fan of freitas (before he quit against corrales) and I had him down on my scorecard (even though the judges didn't but we know how judges work). I didn't want him to lose or get a gift decision. I wanted him to win legitimately. That last round knock out was awesome.
2. Morales beating pac. I was a huge Morales fan and hated Barrera. After pac destroyed Barrera, many people thought he would easily beat Morales. He was supposed to be the next big thing (which he did become) but Morales put him in his place for that fight at least.
1. JMM knocking out pac. I thought that JMM won the first 3 fights. The first and third I thought he was robbed and the 2nd was really close but I had JMM winning although it wasn't a terrible decision. I was so happy he could finally get that win without the judges robbing him again.
