I believe LA opted up last year when they would have been just below the 7A/8A cutoff line.I don't see where LA opted up this year on their own. Looking at the below list of schools the only two that opted up were ESL and SR. LA is already an 8A school. They have almost as many young men as MC and SR together.
It was not their intention by any means, but when they dropped a week 9 decision to MC, it created a situation where MC could win 7A and LA 8A. Had they not opted up, us fans would have selfishly gotten an MC-LA rematch in 7A. Instead, they both cruised to titles in their respective classes.
I believe they wound up in 8A naturally this season.
