A question about Brock Lesnar?

What do you think of him as a person outside the octagon? For those who want Lesnar beat, what do you think those other guys like Shane Carwin, Velasquez, and Royce Gracie (in his prime) would have to do in order to stand a chance to beat the big, and seemingly Invincible Fighter, and arguably the world's strongest man alive, and the world's number one fighter? From my view, these fighters will need to have excellent fighting skill and techniques, as well as speed, and a great deal of stamina to wear Lesnar out. The fight would have to be kept on the stand up mode, as Brock being the more powerful fighter will win a ground pounding wrestling match, or slugging match almost every time. Brock Lesnar may seem invulnerable since he's so big, and strong and he uses it very well to his advantage to beat his opponents in MMA and wrestling. If Bruce Lee were around today in his prime, and Lesnar were to fight each other not in the UFC octagon, but in a real life and death fight with Bruce defending himself when there are no rules or regulations. I'll bet Lee as in excellent physical shape as he was wouldn't be able to compare with Lesnar in a ground wrestling, or a slugging match. He'd have to stay away from him, and rely on his superior speed, skill, and flexibility to have any kind of chance to beat him. I think Brock Lesnar CAN be beat by anyone sooner or later who is a much better fighter at any given time, but he like boxing's Mike Tyson in the late '80s seems unbeatable due to his natural brute strength and athleticism. He's just hard to beat since he can certainly dish out and take a lot of punishment in order to close in on his opponents in the ring.
