I think you are mistaken. One of the three that was out before averages 2 points. McCormack played tonight. Not sure of the other player. USC is very good....and I hate to say that. Kansas is always overrated
Oregon State played great down the stretch including winning the Pac 12 tournament against some very good teams. Late bloomers for sure and are playing great.
That right there points to your impeller. At higher speeds, water is forced into the drive and the impeller blades flatten out so they are actually doing less. At low speeds where the impeller does more work, it is not pumping enough water.
