1. Players who touched their teammates more had higher "Win scores," defined as "a performance measure that accounts for the positive impact a player has on his team's success (rebounds, points, assists, blocks, steals) while also accounting for the amount of the team's possessions that player uses (turnovers, shot attempts).
