Cung Le has better Striking, and I'm pretty sure he has better wrestling as well. What Franklin has is better Cardio, and a mind-boggling advantage in experience. Probably a marginally better ground game too.
Rich can try to tire Le out against the cage, but I don't think that will be as easy as people are making it out to be. He can try to stand with Le, in which case he will have a puncher's chance. Le's defence isn't great and he doesn't react well to being hit. All things considered that scenario still favors Le though.
I think it's close. I'm obviously in the minority though.
