I like allistair a lot and have seen all of his fights. He is a great kickboxer but he doesn't utilize his skills where he needs to. When I see an opening for a 1,2 lowkick combination he will lowkick without setting it up with a punch and in return gets rocked by a straight, hook, overhand, etc. He is a big strong athletic dude but it seems like one fight he knows it all and the other times he just forgets. I hate to see that happen to the better fighters.
The gassing thing is simple. He is a sprinter. I have the same problem. We are good at finishing a fight early but when it takes to long to we are pretty much done for. You can see that in almost all his fights.
