You think?
Bradley could box his ass off, remember him outboxing Devon (before Devon started crying) and him outboxing Lamont (after Lamont beat him brawling).
Porter can't box at all, he is either dominating you physically with his pressure and rough housing or he is being outboxed, there is no in between.
That said I agree, against punchers or boxer punchers he suffers because his lack of skill is exploited and he pays for his mistakes.
To put it lightly ive never been high on Bradley boxing skill wise..the only time I was impressed by his ability was against JMM..and that was after the ruslan fight so boxing was the wave for him lol...and he did that impressively..but the shyt he was doing at 140 was effective as shyt even if I didn't like it
