the coach's job is to device the system they play, to win,
the players job is to play the system, to entertain.
the management's job is to create a entertaining product for their fans, to drive profit.
the fans job is to pay, to consume the entertainment.
if you are paying to watch something as boring as that 1-3-1, its not anybody's fault but yourself, just tune out. If they see a drop in revenue, the league will do something to make them open up. kind of like the trapezoid and 90s devils hockey.
