That's why football actually is a good corollary to war. It's not as important or anything, but everyone is assigned a physical chore and you're only successful if everyone does their job.
Just on a screen pass, you have linemen initially blocking for just the right amount of time before releasing to get out and upfield, a QB often having to drop a pass over D-linemen to a RB who had to mimic some other play before receiving the ball...and THEN the footballing happens. Linemen have to just bum-rush defenders and smother them or at least get their head across, the RB has to read those blocks and sometimes speed past his blockers, if there's heat from behind. WRs this whole time start out by seeing how far they can trick DBs into following them downfield, before turning into blockers themselves - a skill they're not practicing all that much.
