Conor being 2 division weight champ means nothing in the long run cause UFC hasn't let anyone do what he has done
It's been my long standing opinion that Conor will never fight at 145 again. Even his team was laying seeds of that before the Aldo fight. He was having trouble making the weight. In addition, he's pretty much beaten every contender at FW(aside from Edgar), so there's no real incentive for him to drop back down to 155.
He's got a lot of intriguing matchups at 155. He can fight Khabib, El Cucuy, Diaz again or just take some time off. He's fought 3 times since the Aldo fight last December.
