Eric, I read again what Headup said and I think he is basically making the same point as your statement.
Apples and oranges. A dual that is undecided heading into HWT is MUCH better attended than a tournament final.
He never said he thought that Heavyweight was a more exciting style. You are right it is generally slower but that analogy you gave of the baseball defensive game was good.
A boring match can happen in all weight classes even in the faster lighter weights. Remember the 2009 125 NCAA DI title match between Troy Nickerson of Cornell and Paul Donahoe of Edinboro. There was not a lot of action in that match and there was plenty of complaining about it on the national forum after it was over. I also watched the Pre Season College All Star match a couple of years ago where the heavyweight match was probably the most action packed of the evening due to a very mobile aggressive heavyweight with Olympic style experience from I believe Nebraska-Kearney.
I agree the action is too slow in most heavyweight matches. Personally I believe the pushout rule would improve that some. In college I am also not crazy about the riding time rule and would like to see it either eliminated or changed.
