Yeah, I can't figure out how he thinks that would be a good idea. IMO that's one of the worst things that you can do, if you wanna harvest nice mature bucks. At that age, they are still 2 years away from even being able to get an idea of what they might be later on. Even then, they may have a drastic jump in antler growth from one year to the next, which has already been said. I can understand shooting a buck with bad genetics or one that has been injured. Maybe your friend will change his mind about this, I don't think that he will find many that will agree with him.
