Good system beat...but that's a no-no in the league in which I'm commish. Bottom line is it's a cheat.
I posted something under the Ruth/Bonds thread similar to this. As commish, you should think this through. Why is it cheating? Isn't this a strategy available to all players in the league? If the Yahoo! system allows it, and it does not involve collusion, etc. why would you call it cheating?
I call it gamesmanship. If you think it should be illegal, then you should let Yahoo! know about it. Until they actually make it illegal, though, it's not cheating.
Just like the corked bat for Ruth. If he used one, and it wasn't against baseball rules, than it wasn't cheating.
