Maybe my recollection is iffy but my impression has always been that does certain things well (controlling the break, limiting his opponents punch selection and using his physicality to manipulate and turn guys) but I think that's still a fairly limited toolbox as far as fighting in the pocket is concerned. I don't believe I've ever seen him catch and shoot, he doesn't seem to find openings for his punches while he's actually in the clinch (his best work is done while entering and exiting) but most importantly he doesn't really stay there, he always looks for that midrange because that's where his power is. Nevertheless I'll go rewatch the Brook fight sometime, maybe I'm missing something.
