re: Picayune High - #1 Team in Mississippi. Anyone know about them?

Picayune resident here.
I agree with most things in this thread about the town itself. Though it has certainly been improving over the last several years.
Almost another Slidell, methheads included.

Picayune's has almost exclusively been a power running team. Coach Dodd Lee refuses to adopt a 2 minute offense, or, for that matter, more than 2 passing plays.

They have a solid defense, and have performed extremely well all year with the exception of the game against Pearl River Central. They were run all over, but narrowly escaped with at TD in the last few minutes.

They'll cakewalk anyone in their bracket with home-field advantage, though.

TL;DR: No, I doubt that they could beat Hoover or John Curtis. But, as for MS, they deserve the ranking.
