It's an extreme measure to fix an extreme problem the game had out of the box: way too many INT's. Not sure what you're getting at with your "skills are far beyond normal players" comment, unless you're simply trying to create some controversy. If so, cut it out and get real.
IMO it makes no sense to lower everyone's rating to 0. The sim thing to do, as some have mentioned, is to give a select number of players higher catch ratings, depending on their INT ability. But the majority of defensive players should have catch ratings set at 0, or at most in the 1-10 range, no question.
