Have you seen Lesnar fight MMA? He's a completely different beast to the 315lb muscle freak that Angle was shoot wrestling with in their WWE days. He's a lot quicker, has far more agility, yet still incredibly strong. Normally in MMA wrestler vs wrestler fights result in the wrestling being negated, and the fight relying on striking ability. Lesnar would have an experience, power and reach advantage in the striking game, and he proved in his fight with Couture that if he hits you, you stay hit. He barely connected on Couture, yet basically knocked him out, before finishing him on the ground with hammer fists. Also, given Lesnar's jiu jitsu training, he'd be able to use his strength and technique to sweep Angle from the bottom, if Angle could actually get Lesnar to the ground that is. I see no way Angle could beat Lesnar, even with the training. Couture at 205 would be another matter though.
