Steve Javie, without a question. He is the ultimate Jazz hater, Sloan hater. I cannot tell enough how I hate him. Just to remind you a couple of games not dating back too past; Jazz/Spurs game 4 in 2007 WCF, Jazz/Lakers game 5 in LA in 2008 WCSemis. Add lots of home/road regular season games. I will not feel bad if he dies today.
Joe Crawford's acting like he knows and sees everything on the floor, calling fouls from incredibly absurd angles, oh my... he is a control freak. He likes to get on home crowd's nerves. You remember Duncan vs Crawford battle? LOL. He thinks he is great. Easy dude. Fotgot the 2nd worst one: Eddie Rush. How can he still have a job in NBA and FIBA?
From young refs, Kane Fitzgerald, do not like him, unlikeable. Violet Palmer flat out sucks. I have seen nobody pleased with her performance. Rodney Mott is another too much disciplined, no no-sense guy, like a robot.
