McGregor vs. Aldo or Edgar for UFC 200?

After being cleared for action by doctors and medical staff for UFC 200, Conor McGregor has set his sights on defending his 145 pound title. The question; however, is who should McGregor face? Aldo has already been calling out McGregor and clearly wants a rematch. Aldo's insults seems to be clutching at straws to be fair, considering he was KO'd in 13 seconds. But if the original Aldo vs. McGregor was billed as the biggest UFC fight in history, one can only imagine what a rematch would be like.T
