I’m venturing a guess because you don’t want to spend any Jew gold on information is that your “stats” service you subscribe to is more team trends than individual matchups...team trends for stats in the NBA are USELESS.
Just say as a made up example the Celtics are playing the Clippers and your “stats” show that the Celtics OVER is 13-2 last 15 games vs the Clips so you go ahead and fire on the over. What you TEAM analysis wont show (because it can’t) is that Patrick Beverly shuts down Kyrie Irving (don’t know if that’s true) and since Beverly played for the Rockets and Irving played for the Cavs when those team trends accumulated you are firing on the wrong side of that bet.
