No doubt. I rewatched the Proksa fight and he was eating some heavy leather. I think him vs Chavez would be a treat.
Charismatic? No. Or at least I don't see it. Respected? Yes. But obviously when you knock opponents out people are going to respect you no matter what you look like or where you're from. A good example of someone who's charismatic is Canelo. He hasn't done much but when he walks into a building he draws a ton of attention.
