- Andre Ward was not impressive in his last fight, getting knocked down and receiving a gift decision from the judges, needing to use very negative tactics to survive the distance
- Sergey Kovalev was not especially impressive, although he clearly did enough to deserve to win
- Roman Gonzalez was not especially impressive in his past two fights, although he probably should have received a win in his last fight
- Age 35 Gennady Golovkin looked a bit past his best in his last fight, although he's still very good and won the fight against a very strong opponent in Daniel Jacobs
In contrast, Vasyl Lomachenko has been very impressive in his past three fights, completely dominating world-class opponents.
I'm not sure how to accurately sort out the rest of the top ten P4P, but it seems clear to me that Lomachenko should be P4P #1 at this time.
