From the (surface level) lack of credibility of their conclusions I would neither waste any time nor money on a subscription.
As far as your comment "they would ls score more, we would score less", yes, that may be true but to what level? If that game is replayed exactly as it unfolded 1,000 times they make make it a 10-12 point game once.
I also wonder if anything is factored in for the shot alterations Clingan caused (and later their unwillingness to even attempt something from in close when he was there). A layup attempt from 4 ft away may look like an automatic make in the computer but if your biggest concern is a giant swatting it away, rushing a bad shot could be the norm.
