haye fighting southpaw..?

they obviously were joking, but did they reveal a part of their strategy..? just rewatched wlad-sanders, a short fight, but nonetheless wlad only landed 1 jab. Im not about to re-watch wlad-ibra, but as i recall, wlad had trouble establishing his jab and surely wasnt as dominatnt with it, as he usually is against orthodox fighters. perhaps they spotted a weakness or a way to confuse wlad. has haye previously fought as a southpaw or tried switchhitting..? would be a risky and bold move. Haye Does have the speed and athleticism to do it and could also be a way to control wlads jab and reach advantage.
