You know what they say, if you want to beat the champ, don't leave it in the hands of the judges.
That fight, and those scores are a very good example of why this saying exists.
Close fights tend to be leaned toward the champ, regardless if he's slightly winning, slightly losing, or in a draw.
You're correct in the fact that there is a championship bias when it comes to the judges, but MMA media get's it right most of the time. For example, when Shogun lost to Machida the first time, everyone on earth had Shogun winning except 3 judges.
In this case, the overwhelming majority is saying Jones won.
