Pressure fighters fight on borrowed time. It is only a matter of time before fighters like the Baby Bull, Margarito, Hatton, etc. meet an accurate enough counter-puncher with pop and get dropped for their recklessness. Brute force, aggression, and the belief in one's chin are not enough to overcome good footwork and quick handspeed. Secondly, we are witnessing greatness in our time. Mayweather, Pac's incredible improvement over the last couple of years, and Mosley's resistance and speed at his age are all things to take note of. Third, it's difficult if not impossible, unless you're Pacman to alter the style you've used for so long. I think it made Hatton second guess himself and hesitate a little at first and after he ate a couple of rght hooks, (dude had no idea how to fight a left hander. You have your left foot outside of his right, lead foot so you can see the right hook and quickly move your head out of the way, while also keeping oneself as far as possible from the power of that person's left hand), he just reverted to slow, off balanced haymakers and hugging which didn't work. It will be interesting to see what lessons are learned or re-affirmed in the coming months or year.
