Re: K-1 2012 Final 16
Blake was undefeated, but his fight with Cro Cop was only his second time fighting outside of Oklahoma, and his two most notable wins are over a very old Marvin Eastman, and a very old Dewey Cooper, neither of which were ever great kickboxers themselves. Plus, he fights in a very point based karate style, very rarely sitting on any of his strikes. Cro Cop didn't really have to fear the knockout, and won purely on being the aggressor.
No, it wasn't a particularly great win. It just showed that Blake isn't ready for the world scene, and that his style doesn't adapt very well to K1.
