CompuBox was never meant to score fights. It's used for reference, the founder says even for scouting, discovering trends over time, etc. Take their numbers with a lot of salt. Each operator in charge of the fighter can be roughly on point that night or way off. The operators are sometimes former fighters. I'd like to see CompuBox improved and the UFC's FightMetric.
That said, the 2016 CompuBox 'Statistical FOTY' was Crawford. Yes, CompuBox has a Fighter of the Year based on just their stats. Lomachenko was their Runner-Up for FOTY. They both led in 4 categories each and after the Walters fight Lomachenko took over the Plus/Minus list at a +20.9 rating (highest rated since Mayweather's +24.5) as well as Opponents' Total Connect Percentage (lowest). This was published by BoxingScene 2 months ago.

Fighter stats in 10 categories for 2016. There are realistically 9 categories because the +/- list is derived from two of them.
