Andre Ward. Rigo. Ali. Brook. Khan. Fury when he wants to. Pacquiao Marquez pretty much all top tier boxers can control distance well...it's what seperates top tier pro's with standard tier fighters. The very best? Marquez is extremely good given that he is quite flat flooted which comes with his counterpunching style. He controls his opponents with fear of the counter which is fun to watch.
Active fighters right now? Kovalev, Golovkin, Lomachenko, Joshua actually but we need to see him against better comp to be sure, Usyk, Mikey Garcia I THINK. Pretty much the type guys of any division.
Rigondeaux and someone who doesn't get nearly enough credit for it, but is brilliant at it is Kovalev.
Lol, Calzaghe is the funniest guy to me because I cannot figure out WHY his damn slaps WORK. Why is he so effective?! He makes me rethink everything I think I know about boxing. I would be so upset if I boxed him because not only would I get my ass handed to me, but I would do so will getting slapped to death.
