Lee had some pretty good moments, his scrambling was incredible he escaped many submissions that most people would have gotten trapped in, but he was clearly outclassed on the ground. Olivera was slivering around Lee's body like an anaconda eating it's prey, shit was scary. I don't know why Lee decided it was a good idea to take it to the ground as in the previous rounds every second Lee was trying to escape a new submission.
Also the Johnny Walker fight was a huge let down, these russian nut huggers are the shovelers of UFC
