Lucky for Jonny he didn't get a rematch. Johnny went on a losing streak afterward that ended with losing to a gay porn star in bare knuckle. GSP won the MW title. And that's not even getting into the other, uh, issue (avoids stating so post isn't deleted, but knows the evidence is overwhelming).
Robbery and a bad decision are two different things. Not saying this was either, but many here don't know the difference. A robbery is where one fighter dominates the whole fight (or close to it) and the other gets the decision (the term came from boxing). Whether you think this was a bad decision or not, the fight was close enough to not be a robbery. Johnny did more damage during the rounds he won, but that doesn't matter unless you go to Pride scoring. The only think in dispute was round 1, and it was no runaway. GSP won rounds 3 and 5.
