You are right, I watched all three of their fights and it has to be the best trilogy since Ward/Gatti. Vazquez/Marquez are both more skilled than Ward or Gatti IMO, but both were great trilogies. Just look at both of their faces at post fight interviews. These guys gave everything they had.
Luckily, I was able to see both events...the boxing and UFC 82, thank God for the invention of the DVR.
