Boomka, what I mean is that there are definitely some drummers who seem to have a much higher natural aptitude for speed than others. For example - when I was a teenager I had a friend who was not a drummer but could play single strokes much faster than me and was completely untrained. Then there are guys like Tom Grosset who set the world record when he was 16. Now, of course I know that hard work plays the most important part in developing speed, but I do believe that some people have a central nervous system that is better geared towards producing speed than others.
From watching how Mike plays, to me it suggests that he does indeed have a natural ability to play fast, especially seeing as he uses his wrists quite a lot - and that is a lot harder to develop than fingers only.
Of course, I could be completely wrong given my quite limited and untrained knowledge of physiology, I'm just going by what I have experienced and observed.
