Cleaningtheglass.com has an interesting statistic they call "location effective field goal percentage". Here is the explanation:
"If this team shot the league average field goal percentage from each location, what would their effective field goal percentage be? This gives us a sense of the efficiency of each team's shot profile".
The Cavaliers rank 1st in the NBA in this category. IOW, if they just shot the league average from the locations where they took their shots, just average, they would lead the NBA in effective field goal percentage. Where do they actually rank? 14th.
The Cavs are the best team in the NBA at getting good shots. If they were just average at making shots from those locations they would lead the league in effective shooting percentage. But they're such bad shooters they rank 14th in eFG.
