Bradley got power too, but his punching technique comes and goes during fights and a lot of the time he just flails as well. Every now and then he'll throw a good correct shot and drop or hurt somebody (Witter, Abregu, end of Marquez fight) for examples
i dont think bradley is all the way featherfisted either..the problem with bradley's punching is its somewhat amateurish as you said...he doesn't sit on his punches and he's something of an arm puncher...the only punch ive seen him throw with effectiveness is an overhand right...i did see improvement in that aspect in that jmm fight though with him using his legs more when punching..the ruslan fight is prolly the best ive seen timmy punch. cuz no way a featherfisted fighter does what he did to ruslan..he was really sitting on his punches and punishing ruslan in the later rounds
