I would bet on Frank Mir winning this one.
Brock Lesnar's power is overrated, as he has proved in his previous three fights.
Let's start with his fight against Mir. Yes he knocked down Mir a couple of times and then pounded him with his "power punches" and elbows both the times, but did he finish the fight?
NO...why? Because he can't, and because that's exactly how the fight went.
Mir made Brock tap. For a guy who some people think have a "weak" chin, Frank Mir didn't even look dizzy after getting caught. He was pretty active on the ground and was going for submissions while not avoiding a lot of brock's punches, so Brock did land those punches which caused minimal damage.
In his fight with Heath, Brock used Heath like a power punching bag for three rounds, and rode him like a pony, but people forget that Brock still did not finish him. He did his part of landing the punches, but there was not a lot of power in them
Before this fight if someone would have told us that Brock would land the punches like he did in the fight, then we would say the fight would end in the 1st or the 2nd round with heath getting ko'd or tko'd. That didn't happen.
I am a big Randy fan. Before the fight, when he said that age is not a factor, I believed him (we all did).
We want him to win, but we all know that is not true now. If anything, age does play a part in your endurance or your ability to get hit. Most of the fans, both old and new, see Randy as a legend who is still a tough nut, but if you followed his career closely you would notice some interesting things.
He started as a HW, and as he got older he he made the smart switch to go LHW after his fight with Chuck in 2003. He remained there until 2007 when he moved up to fight Tim Sylvia and Gabriel Gonzaga.
When you spend so much time in LHW and then make a switch to HW (especially at 45 years old) it has got to affect your endurance.
To Brock's credit he improved a lot since his last fight, and he finished him off.
Nog looked wasted in the fight against Mir. Mir had the chance to finish him and he did finish him. Brock, on all occasions, had chances to finish off wasted opponents too, and he didn't really impress me.
If Brock does KO Mir, I wouldn't be surprised though. Not because I think Brock has the power to do that, but because I think that anyone in MMA can KO anyone else with one lucky punch.
On the other hand, if Brock shows up and delivers the performance that people say he is capable of, then he will win a lot of respect.
