There is that chance. Maidana is not very skillfull but he's nowhere near as bad as some are making him out to be. Prscott is AWFUL-many leagues below Maidana and he still managed to land. I know Khan's improved his defence since then and fights safety first but he can still make mistakes and is not a defensive genius. I would put my money on a Khan win but I wouldn't be surprised if he got cracked again.
