Fedor already had educated punches, the only thing i see is that he tightened up his strikes; an made it a point to put his punches together better.
But the main thing that lead to his success is that he was not scared to pressure cro cop, it's the same situation as chuck; people spend to much time staying outside trying o figure away to get him down w/out getting hit. As a result their shoots are not deep enough, an they can't work in to tieup their opp and brng them down.
The people who have the most success in taking guys like that down are people who are willing to risk taking a shot or two to get the takedown or more importantly once they are in range, they are not willing to fight for the takedown. They fear getting hit and opened up for the ko, an u can't be that way; cro cop and liddel are to good to get taken down w/out some sort of resistance or struggle and within that struggle u gonna get some heat. IT's just a fact...an if u can't accept that then u can't win.
Fedor did not mean or want to trade w/cro cop but he knew he had to a)keep cro cop on his heels and not let him dictate the pace or range of the fight because cro cop is a better..more athletic..tech sound..and exp striker... he had to make cro cop uncomfortable, which meant not letting him get confident and open up. b)he had to keep his hands moving, yeah he might get countered; but he had to make cro cop pay some sort of attention to def, otherwise he would open up and ko him.
He did what he had to do, to keep cro cop off balance and uncomfortable; once cro cop gets in his zone he knocks people out...the people who have beaten him or even taken him down are the people who applied "intelligent" pressure and lots of it.
Everyone knows the book on cc..attack..go hard..and apply pressure and he can and will get beat, nog applied pressure..took a beating..took him down..and then armbarred him... randleman muscled him..exploded on him and then koed him... fedor pressed him...hit him..controlled him...then decisioned him...
PRESSURE IS THE SOLUTION TO THE CC PROB, U gotta have heart chin and toughness; an if u have enough and fight smart u will beat cro cop every day.
