Penn could also say that they've improved since Week 3.
There's certainly nothing wrong with thinking Fishers, Westfield, and HSE would be Carroll head to head. Given past performance, that would be the best bet. Anyway, the Crown Point/Carroll winner facing off against HSE/Westfield will have some intrigue to it.
From what I remember about Carroll's game against Snider, they're not flashy by any means. They just get the job done. Quality all over the field.
