Johnson if he didn't cut water. Ali if he didn't spar full contact. Monzon if he didn't smoke.

Giving up any number of cigarettes is going to more than slightly reshape any pro athlete's topography. From a pack or two per diem to zero is obviously going to be mountain-flattening results, but even the difference between smoking a pack a week and cold turkey, if you're someone whose stock and trade is stamina like Monzón's, that's going to at least smooth out the odd hillock.

Evenness wasn't an issue for him, as like you said he was consistent start to finish, but the coal he was able to stoke bell to bell surely would have multiplied.

 

Carlos did fine on the ciggies.
