i usually say that the larger the tree larger the buck. but sometimes the larger bucks would rub smaller trees like red said. on the property i hunted this year i only saw small trees rubbed then my dad got a spike and we saw a small 4 and big 6the next day we went out went to the pines and saw a much lager tree newly rubbed. that deer was remaking his property. he was a 9pointer that herd dads grunt calls and came down for a fight and i got him. he was my first deer so i learned alot this year.
good luck with getting the deer
