I'm not going to go to the effort of verifying those numbers, but assuming they are correct...
Net calls in team's favor in final two minutes per close game (by NBA admission):
Lakers: +0.42
Warriors: +0.33
Celtics: -0.05 (approximate, number of close games not listed, calculated for 20 close games, will be ~0 at any rate)
T'Wolves: -0.07
Pelicans: -0.11
Bulls: -0.17
Jazz: -0.24
Kings: -0.45
Now, there's 22 more teams, so we can't say for sure we're getting hosed the worst...but from among the teams listed we're nearly twice as hosed as the next-worst team.
