Soundwise...
Quality-wise no black marching band matches Cookman. Maybe TnSU(not in the SWAC im just mentioning them), AAMU and JSU come close. Well JSU comes close by their big band sound, which doesn't have the same "focus" as Cookman's complete sound.
Field show wise Cookman has been a very consistent crowd pleaser. They gets house...wit gator shoes on.
FAMU CAN get house and they sound above average on the field now. (Trumpets still needed work).
No one will change to be "like" either of them. Maybe some swac bands will change to their own older ways concerning their own quality of sound or better quality but that won't be because of FAMU and Cookman, it's because to recruit now you need much more than name and tradition to get kids to march in a marching band for scholarships. Like my school...we aren't a small school at all by enrollment yet we won't get alot of recruits recruiting everywhere every other similar band recruits. Cookman and FAMU don't exactly recruit everywhere any SWAC school focuses on anyway.
Now if swac bands besides JSU and AAMU want to take something from Cookman, it would be tone quality. All your power is...cute...but you get more with better tone quality. JSU wasn't matched by anyone at Crankfest because their TONE quality was better than everyone there. They didn't have to work as hard to be that loud by effect and didn't lose any quality or volume and didn't play anything without attacks that made things powerful. I won't keep boring people with the things I learned from different teachers and playing professionally but FAMU and Cookmam make it more interesting.
