See, this is why people are calling you delusional...
First of all, calling Dereck Chisora an exciting talent is so widely off the mark that, where this an archery competition, you would have taken someone's eye out. Dereck Chisora may be a ggreat fighter when it comes to biting some guy's dick off in an alley, or beating his girlfriend's face to a pulp, but he's not a great fighter in the ring. In fact, he's not even a good fighter. In fact, he makes Primo Carrera look like Muhammed Ali. I mean what is his claim to fame? Beating some guy who barely beat some guy who may have driven a cab?
Now on to John Ruiz. Who apparently was a VERY well respected fighter. Well I got new for you son. He wasn't. In fact, not only was he a categorically mediocre fighter but he was an old categorically mediocre fighter. A bunny rabbit hit by a pick-up truck would have offered as much resistance to David Haye.
And finally we reach your statement that neutrals "all over" regard David Haye as an exciting fighter. If you mean all over England, you are correct. But if you mean all over the world you should bear in mind that in several places the name David Haye is synonomous with "The Ducker". Now don't get me wrong, Haye is fast, and fit, and he likes to throw leather... BUT he has fought absolutely no-one even approaching the level of a Klitschko. So if you're going to watch the fight I suggest leaving the cans at home and bring a pallbearer.
