Florian did a great job of nullifying BJ's striking for the most part. He kept his lead arm extended and continually pawed at BJ while circling left, taking away his jab, arguably his most effective punch. Then to make sure he didn't run into one of Penn's sledgehammer right hooks he kept throwing head kicks to keep that hand busy.
Florian's entire game plan, however, revolved around wearing BJ out by using those tactics to stall and pushing Penn up against the cage like St. Pierre did. The only problem is that BJ was in shape, and Florian has neither the strength nor the wrestling ability of GSP. It was only a matter of time before Florian was finished, despite his intelligent fighting he was completely outclassed.

As for Anderson Silva, well he blew my fucking mind. I'll leave it at that.
