All great stuff! Coming from outside of NoVA should help you with JMU and Eagle Scout should also help (and congrats on Eagle! Both my boys are Eagles and I know how much hard work - for years - that can take!)
I do think you have a chance at JMU, so I didn’t mean to suggest otherwise. I’ll just tell you the same thing I’m telling my HS Senior child - admissions has been really wacky the last few years, so it’s just good to have a good handful of options that all make you happy.
If you want a safety that is in state, has business, has football and marching band, do take a look at ODU. Football isn’t as big as it is at JMU, but it’s there.
I’m not sure what your budget is, but if it can stretch up a bit, you could also consider Appalachian State. It’s in North Carolina so you’d lose the in-state tuition, but if you are looking for a bigger school with football and marching band and a solid business program, then they might fit that niche for you. App State is in Boone, NC in the mountains - it’s absolutely beautiful country.
