Why are we talking about a fight that happened in April of 2007? Both fighters have changed since then. GSP went on to win 12 fights in a row after that. Serra lost to GSP in a rematch and went 1-2 before retiring.
The fight does not tell us much about GSP, unless you believe humans are static and fighters are defined by a single fight more than 10 years ago.
I have a theory - you hate GSP and want to create a thread to emphasize his most humiliating loss. Congrats. It happened. George Bush was president at the time, Conor McGregor was 19 and hadn't even started his professional career, and Randy Couture was the UFC Heavyweight champion.
You need to move on. Talk about something relevant. I've seen the this 1000 times. I appreciate that you think it triggers GSP fans but it only makes you looks petty and stuck in 2007. Next you'll be talking about Tim Sylvia v. Jeff Monson and UFC fighters who wore shoes in the octogon.
