George St. Pierre vs. Thiago Alves:
I'll begin my predictions for these two main event matches, with George St. Pierre and Thiago Alves. George St. Pierre is going into UFC 100 with a record of 18-2-0 against Thiago Alves's record of 22-4-0. Pierre has a height advantage on Alves, and they both weighed in at 170 pounds.
Watching this fight, I expect nothing short of a war between these two great competitors. We've seen numerous amazing fights out of both of these fighters, such as George St. Pierre against the likes of BJ Penn, Matt Sera, Matt Hughes, among others. And on the other side of this bout, we have Alves who has also had numerous amazing fights against the likes of Penn and Sera.
I would have to give my prediction for this match to George St. Pierre, a well rounded fighter who I believe has had a little more experience then Alves, based on the fighters they've faced. George St. Pierre is very well rounded, but has to watch himself against Alves's strikes and is very dangerous and skilled in Jiu-Jitsu. Pierre will have to work his ground game, and watch the submissions, while in return possibly look for his own.
My prediction: George St. Pierre
This fight branched from their first encounter, which happened to be Brock Lesnar's very first match in the UFC and only his second MMA fight ever. After a dominating MMA debut in Japan, Lesnar decided to make the jump to the competition in the UFC, which in return would have him face off against the dangerous submission machine in Frank Mir. Their match showed that Lesnar had the upper hand, and even a possible stoppage not called when Mir didn't defend himself for about twenty to thirty seconds, then Mir caught the ankle and submitted Lesnar to give him his first lost.
After another win against the Texas Crazy Horse, Lesnar found himself against the then UFC Heavyweight Champion in Randy Couture. Couture had been holding out, with legal issues with the UFC, and finally returned to the Octagon to defend his championship against Lesnar. Lesnar would enter the Octagon that night, and leave as the Heavyweight Champion as he scored a KO victory on the legend Randy Courtue.
Mir also would be very successful in the time between him and Lesnar's first fight. Mir would claim the Interm Heavyweight Championship, and will defend it against Lesnar and try to unify it.
I have to give the win to a hungry Lesnar though. He's proven in all of his fights so far, that he has what it takes to just dominate his opponent at free will, and he's quick and agile while doing it. Not to mention he has the hands that resemble cans of ham that he can throw pretty quick. I think he'll be much more cautious of the submission from Mir, and won't be too quick this time to try to finish Mir early. I think it'll be a battle, but Lesnar will come out on top as the Undisputed Heavyweight Champion.
My prediction: Brock Lesnar
