This is an excellent fight for the vacant WBO Light Heavyweight world title. Joe Smith Jr has come back from hard losses and has consistently won as an underdog to get to this position. Maxim Vlasov has won three fights in a row since losing at Cruiserweight and has been operating at world level for a while now.
Maxim Vlasov is the bigger fighter and will likely try to box from range the entire fight and use his boxing skills to win a decision. Joe Smith Jr is going to come forward and attempt to chop down the tree with his power and underrated skills himself.
I can see this fight going either way but I lean towards Joe Smith Jr winning a decision due to landing the bigger more impactful punches.
