Usually the smarter striker wins it isn't random. Condit/Diaz is an example of this in one way and Cung/Franklin is in another way. The former took away what his opponent does best while standing the latter used what his opponent was doing to knock him out.
I know what you're saying, and I agree, but I'm not sure the Le/Franklin fight is the best example. I still think Franklin wins that fight 4/5 times, he just got caught.
