it's very simple. because he new he was going to get the all time record and was jealous that sosa and mcgwire had the big battle for the single season record and he was left out.All good points, I just don't understand why he went with the enhancement...???
I GUARANTEE if maris still had the single season record, bonds would not have juiced. but thats how mcgwire did it, so he did it to.
