Close enough fight, Brooks performance is wile overated he didnt land much punches either, didnt really discourage porter from coming in. Porter just gassed agfter trying to hard to knock him out, wouldnt mind seeing it again.
One of the biggest flaws of Jo Jo Dan is that he doesn't have enough punching power to make his opponents (world title quality oppositions) respect him enough. He has high work rate but not much pop in his punches. So Brook might walk over him in 8 rounds or so, and be given a British stoppage(TKO)
