Which fighter do you feel that their counterpunching skills aren't as talked about ? I feel Josh Taylor, Ugas and Nietes are underrated in this department. You can add some unknown fighters too who you didn't expect to counterpunch well, my pick for this category is Jason Quigley, not world level for sure but he has got a good skillset and isn't afraid to let his hands go.
The guy in my avatar is a bit underrated in that aspect of the game. Also Thabiso Mchunu and Pedro Guevara (what happened to him ?).
