Georges St-Pierre and Nick Diaz waged war in the days leading up to the main event of UFC 158.
The bout was fueled by bad blood and animosity, and fight fans were promised a different, darker side of the reigning welterweight champion.
We were fooled.
Instead of a bloodbath, viewers were treated to another "business as usual" performance by GSP, resulting in a decidedly lackluster main event.
Making matters worse, Carlos Condit and Johny Hendricks amplified the evening with a Fight of the Year candidate just moments before Diaz and GSP set foot inside the Octagon.
The moment was perfect.
The fight itself was not.
In fact, the featured bout at UFC 158 was the worst main event thus far in 2013.
To be fair, 2013 has met—and exceeded—expectations so far, and GSP vs. Diaz stands as the only real disappointment.
GSP proved once again that he can take down his opponents at will, avoid submissions and rack up enough points to earn the judges' nod.
It's getting old, and, especially whenever the fight was billed to be so much more, the result is not satisfying anymore.
GSP's dominance is clear, and the fact that he manhandles his opponents for 25 minutes is mind-boggling, but you can only re-watch your favorite movie so many times before it starts collecting dust on the shelf.
With the unanimous-decision victory, GSP broke the UFC record for consecutive cage time without a finish, a mark that now stands at 150 minutes.
I don't necessarily need a finish, either; I just want to see some variety, some semblance of the champ trying to finish a fight.
As it is, though, GSP did what GSP always does at UFC 158, and the result was an utter disappointment.
It was the worst main event of 2013 thus far, and, with the way the rest of the year is shaping up, it might just stand until December.
Unless GSP fights again, of course.
