Terrible judging decisions are an unfortunate part of boxing. Timothy Bradley by split decision over Manny Pacquiao in June 2012 caused tremendous outrage, and justifiably so. But it wasn't as terrible as Courtney Burton over Emanuel Augustus or Joel Casamayor over Jose Armando Santa Cruz.
In my opinion, Bradley over Pacquiao, bad as it was, wasn't even the worst decision of 2012.
The sad fact is, lousy decisions are so commonplace, there are at least 10 more that didn't make this list that could easily be substituted.
Judging boxing matches is very difficult. The officials at ringside are making their assessments in live time, without the benefit of punch stats or instant replay.
Still, sometimes they get things so wrong it's impossible not to suspect either incompetence or outright corruption.
