I was just looking around here for some clips and stumbled across this video. Interesting takeaway was as I was watching, particularly the 2nd half highlights how well Freeman boxes out consistently. Looks like that player had at least 55 lbs on him also.
Does not surprise me that he had 9, surprises me more that the other fellow had the nuts to question his boxing out by putting up rebounding numbers that those who don't get the nuances can't fully appreciate.
