I judge all fights on punchstats. Hands down the most reliable and infallible resource to determine a winner.
I use it and compare it to the judges cards when the scoring stinks. If one guy out lands the other, and there wasn't a significant punch in the round the one who threw and landed more + controlled the action should win that round. This fight looks pretty close going into the 11 the round, however having Canelo up two rounds ( As two judges did ) after 10 rounds sort of stretches it a bit. Canelo seems to get all the close rounds and some rounds he did not deserve. Does anyone have the full cards on display? As for punch stats they pick the winner correctly something like 90% of the time on decision fights, which is better than the official judges as a group.
I think they are on point generally speaking, but not technically. They miss punches but in all fairness I've learned sitting up close one can miss a lot that is on the other side.
