I had Pernell winning 8 rounds to 4, but it could've even been 9 to 3. Whitaker clearly outclassed Chavez, it should have been the crowning moment of his career, and he was completely robbed by two judges who were either blind, corrupt, or both. One judge had it 115-113 for Whitaker.

The weight had nothing to do with it. Sure, Chavez was moving up in weight from 140, but Whitaker wasn't a natural welterweight either. His natural class was 135 and he moved up in search of bigger fights. Prime Whitaker outclasses prime Chavez at 135, 140, 147, 154, wherever.
