How can you think Ali was the most exciting if you're talking only boxing and none of the outside stuff? I've seen just about every one of his fights and I can tell you for every "Thrilla in Manilla" or "Rumble in the Jungle" there were about 5-10 "jab and grab" or "run and gun" fights that were anything but entertaining.

I guess mine would be...

1. Tyson
2. Manny Pacquaio
3. Arturo Gatti
4. Julian Jackson
5. Aaron Pryor

It's hard to pick a guy over Tyson, how can it get more exciting than a guy with that kind of power and handspeed who throws every punch to knock you unconscious. Julian Jackson was that way too in a middleweight form.
