The work rate and pressure of Maidana would really get to Kell,I think if he cant get Maidana out of there within six he loses.Thurman is a much better fighter than Kell imo just look at the guys hes fought compared to Brook and hes only 25,he looks to have everything good chin,lovely movement,picks his shots very well and has serious knock out power in both hands.Porter is not really a big puncher,he used a very good game plan to beat Devon by roughing him up and not letting him fight at his pace.I think Brook could keep him at range because he hits a lot harder than Devon and maybe get a decision but even still its a big ask. Bradley and Mayweather are out of the question though,that we can agree on.
