The new main event of UFC 146 will take place between former two-time heavyweight champion Frank Mir and current champion Junior dos Santos.
Frank Mir comes into this fight on a three-fight winning streak and is looking to become the first ever three-time heavyweight champion in the UFC. Mir has excellent strength and is deadly on the ground with any type of submission. Mir has a pretty good stand-up game and has above-average takedown skills.
Junior dos Santos should probably be the most confident fighter in the UFC. He has defeated every challenge put in front of him during his UFC tenure and done so with relative ease. JdS will be going for the knockout in this fight and will not want to go to the ground at all.
JdS has a clear striking advantage but should be wary of Mir's power. JdS hasn't fought a more complete fighter in the UFC, and if Mir opens up his hands, he could be very difficult to deal with.
Mir will be the larger heavyweight in this fight, and that might be very important if he can move JdS around the ring. He is adept at using trips and tosses to get guys to the ground, and if he grabs onto a limb, he isn't letting go. If Mir can get into a rhythm on his feet, he can be very effective with punches or knees and has the power to seriously threaten the title reign of JdS.
As with any Mir fight, he needs to come into this contest in-shape and ready to go five full rounds at JdS' pace—not just his own.
JdS will want to keep his distance from Mir and use his superior boxing skills to earn a victory. There isn't much else to say about Junior dos Santos. He is going to punch, plain and simple. JdS has seemingly faded at times during the later rounds of his past fights, and if Mir can drag him into the deeper waters, JdS may find himself where he doesn't want to be.
This looks to be a surprisingly great fight that could go either way but does favor the younger Junior dos Santos. JdS is very capable of landing some powerful shots that could put away Mir very early, but Mir has shown over and over again that it's going to take quite a few shots to finish him.
Prediction: If Mir can survive the first and second rounds I look for him to win by 4th round submission (Guillotine Choke)
