Used to think so but then about five years ago seen a small six pointer really work over a nice size tree. Now one thing I try to look at is how far off the ground is the scrape? This will not really determine the size of the rack but help more with age. If the scrape is close to the ground its a young one but if its higher off the ground it is an older deer. But again this has nothing to do with size, Also I voted no.
You are getting your terms mixed up. A tree that has been worked over by a buck is called a rub. A scrape is where they paw up the dirt and make a bare spot on the ground.
And no the size of a scrape does not correspond to the size of the deer, or the hunter,that made it.
