To answer the main question:
This is the first time in as long as I can remember where the ENTIRE staff has been retained from one year to the next (in terms of caption heads). The drill writer was given more than two days notice this year (unlike last year), the brass staff is amazing (as always), the drum staff is working wonders, and the GUARD. The guard has quite stepped up their game this year. A pretty even split between vets and rookies, but they're all rocking their work and will continue to "get it". That being said, the kids are loving this momentum, so I don't think the spirit will be on shortage anytime soon.
tl;dr - Expect big things.
