I don't think stevenson is going to go in and wing like Rodriguez, leaving himself wide and blown out down the middle. His trainers just going to have him jab Williams so he never gets his feet set and then line him up for the left hand. Its just a matter of how long Williams takes to walk into it or slow down to sitting duck level.

Williams was beat and winded at the time of the stoppage against campillo. (possibly broken nose so i wont begrudge him too much on the stamina issue but he hardly looked like the picture of determination at that point)
