I don't think the gloves make a difference as floyd is a master at avoiding taking the blunt of a punch. He can avoid the elbows as well.
I am less convinced he could quickly learn to adapt to kicks, but I wouldn't be surprised.
I don't think he could learn to defend takedowns or the groundgame at this point. Those aren't really Conor's strong suits, but he'd have a huge advantage.
So, full mma it's all Conor. Kickboxing... it's a toss up but favors Conor. Boxing Floyd kills him.
