It's no wonder Cain's style is hustling and relentlessly attacking. He has no choice. He has the same short, stocky bodies of Tyson and Frazier. To get past their opponents' superior reaches, they had to really hustle, willing to take punches to punch, constantly ducking and moving, relying on their speed to get close. But once this speed is gone, they're like sitting ducks. You can see it in the fat version of Tyson. Cain is fast but not quite as lean, agile and nimble as a young Tyson. You saw him trying the same bob and weave thing in the last fight with JDS, moving jig jag pattern like Frazier with little effect: he could not get close because he simply did not have the kind of speed required for that game plan against someone like JDS. Unfortunately for him, JDS's power is highest in the beginning so aggressively putting himself in range for JDS's fists speed up his demise. But what other choice does he have? sticking and moving hoping to tire JDS out? what else is there for him to when this fails?
