I have not made an actual count of this situation, but I have seen quite a few pictures from the early competition
like this. they show the drive team and coach all looking up, presumably at an attempt to hang a tube. This is a waste of eye-power. There must be something else important going on on the field. At the very least the coach should be watching traffic or scouting for the next tube.
I mention this here in analyst discussion to offer something else they could do - remind players and coaches to play, not watch, the game.
