It's just a hypothetical question. I wouldn't advocate that. In 2012, Aloca HS had an enrollement of 536 total students. Of those 536 students, 193 or 36% were out of zone students. That's a very high percentage. How many of those 193 played on the football team? Remember, it only takes one or two to make a big impact, especially in HS.
You can see how outsiders look at alcoa's dominance in football over the past several decades coupled with OOZ student numbers like that and wonder, can't you?
