One thing people forget is that Brock was a national Division 1 wrestling champ...so a 270lb, mean, extremely strong, excellent wrestler will pose problems for a lot of people.
We need to see Brock fight someone that is going to avoid the takedown and test him on his feet. I think Brock should fight Gonzaga next. He may also have problems with Kongo. I'd love for the UFC to bring in Barnett or Fedor, both of those guys should beat Lesner.
I'm fairly certain Randy would have beaten Brock 8-10 yrs ago. Besides the 1 takedown, Randy was actually controlling all the standup grappeling in their fight...at 45-46yrs old.
