Your observations are very true IMO. Given I have played with these bulls for numerous years now, i can say with confidence I would have noticed this bull before last year if he was indeed older. The big boys are very aggressive in this area and fight very hard. To the death at times. Last fall the two biggest and meanest bulls met their demise by rutting too hard. With those two nasty bulls gone, there will be some serious game play this fall by the younger bulls to take their place.
