Good thought, obviously the fight being in Madison square Garden gave it a much bigger spotlight Stateside than any other recent HW title fight. It certainly must have hurt any chance the division had of gaining momentum given it was so utterly shit.

To answer your question however I would say its extremely unlikely. Neither Wlad or Sultan are consistently exciting; and neither have the sort of persona that would really capture American viewers, even aside from the massive obstacle of being foreign.

Whilst perhaps being besides the point, Wlad isn't really the kind of fighter who would ever be in a total war. For comparison though, his first fight with Sam Peters was exciting and back and forth a a lot of the way, and was also held in the States. His loss to Lamon Brewster was as well, but I doubt either fight did all that much to sway public interest. Hell Brewster was even an American to boot, AND he blitzed Golota in a round right after Wlad, and then..... exactly.
