I'd imagine the play calling was mostly scripted, or looking for specific actions and corrections. Like, "we're gonna run Z-43-out at least five times today" and "hey, call that play again in a minute, I want to see something" or "call a couple of run plays to the left side of the line, the defense needs to make an adjustment."
So not a very good indicator of what play calling might look like in a real game. I wouldn't try for any take-aways.
