Jones been ko'd twice in 54 fights down only 3 times does'nt really make his jaw glass i put the ko losses down to him coming down in weight to fast before first Tarver fight after Johnson ko loss he managed to go full 12 with Tarver the 3rd time yes Calzaghe has beaten Jeff Lacy as you all keep going on about but Lacy is nowhere near the fighter Jones is i'd pick Jones everyday of the week to beat Calzaghe even at 38 UD12
