It was also a bout that was as telling as any for fans.
Barao took the fight in what was a unanimous decision in the end. His ability to endure an impressive effort from Faber was something to watch, to say the least.
Now Barao owns a victory over a highly-regarded star in the sport. It's a feat that puts him on the map as a legitimate top threat and a win that told us a lot about each fighter.
These are the three things fans must take from what was a special fight between two bantamweight studs.
Renan Barao Is A Force To Be Reckoned With
Urijah Faber may have had the plethora of experience in title fights, but it was Renan Barao who secured the win in the end.
The UFC 149 main event was a unanimous decision in Barao's favor for a reason. He came out as the more aggressive and composed fighter. It was exactly what Barao had to do to beat a much more experienced fighter, and he did it to perfection.
Now 29-1 and boasting 29 wins in a row, there is no question Barao will be a contender to reckon with for years to come. He is now arguably the best in the bantamweight class after the victory against top-caliber fighter Faber.
Urijah Faber's Experience Wasn't Enough
Faber may have partaken in the greater number of title matches, but Barao was able to hang with him.
It is fair to say after the loss that Faber has lost a bit of edge. Essentially, he is somewhat past his prime.
Regardless of the 19 title matches he fought in prior to this bout, "The California Kid" couldn't come out on top. Meanwhile, the inexperienced Barao was taking part in his first title match and still was victorious.
Barao and Faber Need a Rematch
Barao was the winner of this top-notch fight, but by no means was he the better fighter in this contest.
It was a down-to-the-wire finish that ended up going the distance. After each round, there was still no winner and it came down to the judges.
Although Barao clearly put up the stronger performance, there is no question that Faber still has what it takes to defeat the Brazilian.
It was such a promising fight that it undoubtedly deserves a second go. It would be interesting to see the adjustments each fighter would make and whether or not Faber would be able to overcome the heartbreaking loss.
