2 guys that do nothing exceptional but do everything well who wins? I would pick Watt purely on opposition faced but Ricky has time on his side.
I like Watt in this fight, especially over 15 rounds. At his best, (unless you were real top drawer like Arguello) he often broke his opponents hearts. Very canny, very tough, good chin, southpaw, good stamina, calm temperament and composure, a fair dig on him, resolute and nearly always seemed to find a way to win. More proven than Burns at top level I would say.
