Not a lot of great inside guys these days. I would say Oscar Valdez, Ramirez, Canelo come to mind. For a big man, Fury can fight on the inside but I would not classify him as an inside fighter. Josh Taylor and Ramirez both had some great moments on the inside last week. Badou Jack is another guy that I enjoy watching that likes to work on the inside.
Badou Jack is a good call but for me its still Roman Gonzalez even though hes slowed down a bit but hes still a master infighter.
Anthony Joshua has a good inside game. His gas tank sucks, 5-8 punches and he is breathing for air and needs to take 3-4 rounds off. This will cost him badly against the best
If Joshua is mentioned here, i should mention someone else, Joshua was little scared when it was going to inside fight with him - Andy Ruiz
Right now Canelo this probably won't be a popular post, canelo has the chin to stand and trade walk through a jab close the gap then let a combo go could be high or low. His movement has come on as well the last few years. Looks very much the all rounder these days. Power inside outside counter. AG can do some great work on the inside but yh is on fumes after 4 rounds. Think Conner Ben might be one too watch the next few years is starting to look really happy inside. No where near top shelf yet see a bit of his dad's fire there worth keeping an eye on
Julio Cesar Chavez was not only the best inside fighter of the 80's but easily one of the best ever. Robert Duran, Mike McCallum, Qawi and Pryor were all excellent inside fighters but they honestly were complete fighters that could adapt to anything.
