Witter is quick but I'm not sure he has more speed then Alexander, at this point Alexander is more active, he's not easy to hit and he puts most everything behind the jab. The boat is sailed on Witter imo, and Alexander while he didn't look spectacular in his last outing he still showed all the things that make those who have seen him so high. Witter got discouraged against Bradley, couldn't land clean and that was facing less speed and fewer punches then what he's likely to get against Alexander. He has pop though, Witter does so who knows but much like the Bradley-Witter fight and especially after, think it's just a story of 2 different fighters on 2 different sides of their careers. And he has to be more active if he wants to win.
