I think it's a rub for sure but I don't think it's from a buck with any kind of large spread, maybe a 4 or 6 point because the tree right next to it doesn't have a mark on it. Pics can be decieving but it looks as though it starts about 6-8 inches off the ground which tells me that it's definately a deer that did it, unless a chipmunk decided to sharpen it's claws.
