Melvin is a bigger, stronger, faster striker than Lawler. You beat him by having great wrestling or subs. I'm sure Lawler's are better than Melvins but not better enough to make a difference. Manhoef is going to smash Lawler, this isn't going to be close.
Both have meh chins and huge power but Melvin has insane combinations and hand speed. Most likely Melvin will destroy Lawler but Robbie has a shot (especially if he mixes it up with wrestling ... which I doubt he will).
