Canizales. His mobility and angles will beat Chandler. There is a gym in Laredo, a city sponsored gym, named after Orlando. On the days that he is there, people come from all over Texas to get a minute of his attention and guidance.
Both of them blew hot and cold. On a night when both are hot? Not sure. Both possessed traits that would give the other problems - Canizales with his angles and combination punching - Chandler with his jab and cross. Gun to my head, I guess Orlando, but I see it basically 50-50.
