FastEddie and Steve: Looks like that buck has the "contralateral" effect. Typically results in a deformity like this when there is an injury to the opposite side of the torso, leg or foot. We have documented this a few times in the magazine. The heaviest buck I ever shot had a similar configuration. The effect usually lasts for a couple of seasons, but it can disappear as the buck ages and, hence, allow the buck to revert to a "normal" rack. Not always, but sometimes.
