Hi,
Coach Walt: I'll be back in five. (I presume he means 5 minutes) Yes.
Asst. Coach: Walt, we're in the middle of a game-
Coach Walt: Just call the damn plays!
What's it mean to "call the plays". (They're playing American football.)
I believe it means 'tell the players on the team what to do next'.
Compare this to soccer, where the players think for themselves. 
Best wishes, Clive
