It used to be that a trilogy was something special in the UFC, reserved for equally matched opponents who have edge-of-your-seat exciting fights. (See: Chuck vs. Randy)
Nowadays, it's starting to seem like every other fight angles to become a trilogy. Whether it's because of bad judging, trash-talking, or lack of marquee match-ups, there has been a notable increase in rematches, and it's not always for the good.
BJ Penn vs. Frankie Edgar stopped just short of being a trilogy, but now we may have a second version Edgar vs. Maynard as well as a BJ vs. Fitch.
But nobody wants to see this fight. The first two weren't very exciting, and I'm not buying a feud based on calling each other boring (making for the ultimate battle of the boring).
It's even looking increasingly possible that we'll see a rematch of Bisping vs. Rivera, a fight that never should have been made in the first place.
This trend has lately made for less interesting fights, because we already know how these styles will clash.
But worse, it clogs up the sport and keeps it from progressing forward by constantly testing fighters against new challenges.
I hope this is a trend that ends soon, and that going forward, rematches and especially trilogies will be reserved for fights that actually have fans clamoring for more.
