Hard to say right now, but on Dec 14th we'll have a better idea. To me, it's all about matchups and timing during the regular season.
For example, Shelby caught Crest early in the season when Crest had a key injury to an all-conference OL/DL player, and caught Crest breaking in a new Soph QB....Shelby won 51-21...Shelby later lost 42-17 to Kings Mountain....Crest defeated KM in the final regular season game...so which of those teams is the best?
I think a better question is...when they bring their A+ game, who is the best team? Which team, when all teams are playing at their peak and without injury, is truly the best, regardless of classification?
Would most likely be a large 4A school, but there are several capable teams on any given night.
