Joe Rogan on boxers entering into MMA

Joe Rogan on great athletes entering into MMA:
I think anybody that got really good at boxing could get really good at anything. I believe it's like what Miyamoto Musashi said: "Once you understand the way broadly, you see it in all things." I think someone who became great at any sport could be great at whatever sport they choose to. I think it's just a matter of the same amount of focus and desire.
