I could see either beating the other. Morrison to me had the edge in raw talent and punching power. Parker seems more stolid but also more solid. I lean towards Tommy I think if we are doing best versions.
Parker by KO. Better boxer with much better chin, stamina and ring IQ. Morrison's power won't compensate the gap in all those areas
Morrison was faster, the bigger puncher,and Parker has a tendency to leave himself open when he throws a big shot.Against that Parker is the more solid with the better chin,and appears to have improved a lot.I'm gingerly going for Parker ,but not with any great conviction.
