I say probably because the fight may not happen within the next 6 months. By the time the fight happens, Lomachenko (for example) may have another great victory and have a case for being P4P no. 1.
theres nothing loma can do in the next 6 months that will put him there.....and even then...the winner of this fight would unseat him even if he somehow took that spot
Kovalev is pound for pound and so is Ward. Theyre both great fighters. If one loses to the other it dosent makes either of them any less great. Theyll both still wipe the floor with the other Light heavies.
