As much as I believe Conor should defend, an interim doesn't make sense. It hasn't even been a year since he won it. Cain won his title then took over a year off. Then he did it again. Also has gone over a year without defending. I think the cutoff is a year imo. If the title isn't defended or a fight booked within a calender year of winning then yeah, make it happen. Personally would prefer the Frankie fight.
