Sanders wins. Chris had skills but Corrie had the speed to reach him and the power to hurt him. He's a particularly nasty matchup for Byrd because not only did Sanders mix his punches up well, he also liked to go to the body with some ferocious body punching especially if the opponent used a lot of upper body movement. Byrd doesn't really have the power to punish Sanders back enough to deter him. I suspect that this one would start out slow because Sanders was a counterpuncher himself at heart, but once things warmed up the bigger and faster man -Sanders- would take it.
Sanders would win here. He's too skilled, too big, hits too hard, and is every faster of hand. Could be a UD or TKO. Byrd does not have the ammunition to hurt him, and can't outbox him as Sanders had a decent skills inside or out. Once Byrd feels Sanders power, he'll be safety first, fight in spurts at best.
