Which one was in your opinion the worst robbery of these fights (yeah'a'now there are plenty of more an these don't necessarily include THE worst of all time). I tried to pick fights that are familiar to most and that were controversial in a bit different ways.
One thing that often makes people cry robbery are fights where one guy dominates five or six rounds and the rest of rounds are close, yet in these fights the scores can be correct if the other guy manages to capture the other rounds with narrow margins. That is why I picked Foreman-Schultz out of these fights: Schultz won "only" by about three points, but to me there was no way he won less than seven rounds, he won his rounds very clear. In Lewis-Holy, you could make a case for Lewis winning nine or even ten rounds but even there I think it is easier to see a draw
