You're probably wondering what is currently the UFC's No. 1 identifiable moment with the casual fan. It's probably Silva's front kick against Vitor Belfort in 2011 or Georges St-Pierre begging for a title shot in 2005. Or maybe it's something relating to Brock Lesnar.
If you ask Weidman, his guess is the fight between Forrest Griffin and Stephan Bonnar that capped off the first season of "The Ultimate Fighter" reality series in 2005 -- although that classifies more as the promotion's most famous fight than any singular moment.
In terms of historical context, few fighters mean more to the UFC than Silva and that's unlikely to change. He'll be remembered more for the knockouts that went in his favor than the one that didn't, at least generally speaking.
But when you look at that Weidman left hook, the element of shock it created rippled through mainstream news outlets. Non-UFC fans saw it -- because of its relevance to the promotion and because it was just a wild, crazy moment in sports.
Depending on what Weidman (and Silva) go on to do in the future, there's reason to believe UFC 162 could go down as not just the knockout of the year, but the most recognizable moment in the Octagon ever.
"That's crazy to think about," said Weidman, who defeated Silva a second time in last Saturday's rematch when the former champion suffered a severe leg injury. "But it's hard for me to think about too many things. I'm thinking about Vitor Belfort."
No. 2: Vitor Belfort KO1 Luke Rockhold, UFC on FX 8
Belfort really took to referring to himself as "The Lion" in 2013 and boy did he maim Rockhold in this fight. This was a spinning heel kick for the ages.
We're going to say it one last time and then we're not going to argue about it ever again: Flyweights carry knockout power. End of discussion.
This fight felt like treading water for Barao -- just don't lose, get the win and secure a unification title bout with Dominick Cruz. If this is how the Brazilian treads water, what's it look like when he decides to really swim?
Many wondered what "The Dragon" would look like at 185 pounds and they got their answer in his middleweight debut: pretty good. Pretty. Good.
