I have seen every Tyson fight currently available to man. Same goes for Holyfield, Lewis, Mayweather, Ali, Leonard, and many many more. I've probably seen every Cotto and Corrales fight (or almost every one)...but its hard to say. I can also say that I've seen 99% of all HBO, Showtime, ESPN, and Fox Sports boxing broadcasts since 2004... either live or sought out on tape delay of some kind. I'll even go so far as to stay up til 1 AM just to catch the Friday Night Fights that I missed. I'm a bit obsessed.
Prince Naseem Hamed. Floyd Mayweather Jr. Manny Pacquiao, I believe...as many as I can find anyway. Barrera, Morales, etc.
Most weekends I'm willing to stay up as late as 6am to catch bouts (or if I've been out drinking, keep on drinking until about 6), big bouts or not. I think I'm a bit obsessed aswell. :good
Tyson 100%, Hatton 100%, Calzaghe 95%, Tapia 70%, De La Hoya 100% there my highest ratios and i've seen plenty more but to many to be naming them all
