I'm not exactly sure what everyone considers to be a B level team...

Okay, at 18U you can safely presume Chill and Bandits are A. Probably IMG and Cheetahs too.

So what is a B level - a good NLL? Sparks? Denison?

If those are B level, most of them have 9 very solid defenders and at least 6 solid hitters.

I don't know of any HS teams - at least public - that have that "high of a floor". 5 strong hitters would be elite in HS.

In other words, I don't think it's impossible to think that a B wouldn't win IHSA, but no idea how everyone else classifies things.

(Those A teams would go undefeated!)
