Oh, get real.
If Barry Bonds had not used his mechanical aids and steroids and gotten, maybe, 600 homers over his career, he would still be a great player and headed for the Hall of Fame. The problem is that the artificial aids, both pharmacological and mechanical, have added to his success, which renders his tying or Aaron's record moot.
There is no way to know how many home runs Bonds would have hit unaided, but it doesn't make much sense to keep track of how many he has hit with all the assistance he has had. I can go out into my garage and put together a potato gun that can lob a baseball out of the park. Watching the ball fly is not the point. The point is what a man can do.
Bonds is doing more than he could as a man. Watching him bat is about as interesting as watching somebody fire a potato gun.
I like my potato gun.
