how good is mayweather in cutting off the ring?

Floyd wont need to cut off the ring, Khan been the idiot he is will come straight in with his one two staight combo Floyd will counter and that will be the end of the fight, Khan dribbling in a mess on the floor, but yeah if floyd needs or wants to cut off the ring he can do it to a high level, but he dose not usualy need to as he lures them in.
