Just cause it's always been done wrong does not mean it should continue. 20 years ago 8 kids got busted for not making weight, many were seniors. A coaching legend was and a administrator lost their jobs and reputation. I'm sure it is happening to this day. Regionals have never been done like this, so things do change.
It's been done this way for regionals in 4A and 321A for years....just new to 5A and 6A.
