Broome's advanced stats (Player Efficiency Rating, Win Shares, Box Plus/Minus, etc.) are also fantastic. He's a very good player.
KenPom's kPOY (KenPom Player of the Year) gives a lot of weight to team stats. Basically, it answers the question: How good does a player contribute to the best teams' success? As you might imagine, Flagg scores very well using that approach.
