Yeah, probably. You could make an argument for Leonard as well. Other than those two, I can't come to think of anyone that's in the competition.
I know not many seem to like Floyd but I think you have to include him and PAC in the conversation. At HW Lewis and Holmes seem to be rated about 3 & 4 consistently so they should both get a look. The ones already mentioned as well
We can throw Ricardo Lopez in there. Possibly the greatest minimum weight of all time. 51-0-1. Though they have a ways to go we have guys like Crawford and Lomachenko that could be a very big deal down the road.
