That's Lesner's problem.  He's a wrestler.  They aren't known for being able to finish a fight.  He's too f'n big not to learn eventually.  Dude's a bear.  I can't stand kenflo, but he fought a very smart fight.  Bastard.   
    
I was pretty disappointed in Lesnar's antics, as well.  I felt maybe a bit of the WWE "showmanship" was coming through and a bit of pride, as well thinking that he's earned his "right" to be there.  Personally, I still don't think he's quite earned, yet.  He's fought two people.  A one-dimensional Hering and a near washed up, up and down fighter in Frank Mir, who he lost to.  He is damn fast for a big man.   
    
You're right, GSP may be a bit too big for Penn.  GSP was bigger than I've ever seen him, now.   
lol  Funny you mention that about Rogan.  My gf and I mentioned the same thing.  Like he hadn't slept all night, shaved in 3 days, or had a haircut in a month.  Trim.  Whatever. haha  He looked rough.  He always looks like he's gonna shit himself when he announces.  Or pop a vein or something.
