What sport was that on TV last night?

[Used 2 B Hu]

ive never really seen until recently in college..the whole teams lines up..then the whole team looks at the sidelines for the play. that is still kinda weird to me
also still trying to figure out how that isn't a false start..i guess they dont come to a complete stop

I've wondered about that move, myself. Not sure why they don't know what the play is when they break the huddle, or at least when they come to the line. Kinda defeats the purpose of going HUNH
