First fight BJ won, it still boggles my mind how anyone thought edgar won that fight. We had about 30 people watching it together and there was about 5 rooting for bj, and rest were for edgar. All anyone could talk about afterwards was how bj got robbed.
Personally I think peak performance vs peak performance BJ would take it, but due to his lack of discipline, BJ had very few peak performances, and it is no ones fault but his own. If you are asking during their "prime years" if they fought, I think either could win on any given night.
