Yup. I'd say the biggest difference from one year to the next is Peewee Major to Bantam Minor. Mites to Squirts to Peewees really happens seamlessly. Peewee to Bantam and Bam! Everything feels different. And, a lot of players just move right up to U14.
Bantam Minor to U14 is probably the second biggest change in a single year. You have a few teams assembled for Nattys, and everything else is a ****show. Nobody cares about the games, it's more about getting ready for HS/Prep tryouts. Those team jacket-wearing-parents are left grasping for straws. "Wait, Johnny missed a GAME for no reason at all? What's WRONG with him? And why is Tyler wearing a red helmet and missing practices?"
To those parents posting in this thread with what you see as "legit" responses, wait. You'll see.
