Never one to shy from a strong opinion, Golden State Warriors head coach Steve Kerr had some choice words Friday for the work being done by NBA referees. The Undefeated's Marc J. Spears reported Sunday that Kerr was fined $25,000 for his public criticism of the officiating.

Speaking to KNBR 680 (via Comcast SportsNet Bay Area), Kerr voiced his displeasure with officials because he felt Toronto Raptors guard DeMar DeRozan got away with traveling during Wednesday's game between the two teams:

How is it that everybody on Earth can see these traveling violations except for the three people that we pay to do the job? I don't get it. It's bizarre. It's a point of emphasis on one particular play and that's when you catch and go ... it's just the one that the officials are taught to see.

But I can literally put together a blooper reel of plays that are embarrassing travels that are just not called. I believe it's a case of they have so many things to look at -- they are looking at defensive three seconds, the contact in the lane when people are cutting through the lane, they're looking at the charge and block circle -- they're looking at everything except what they should be looking at which is the basic rule of the game, which is traveling.

Kerr added that his favorite non-travel calls are when "you see the visiting team travel and you see like a 1,000 fans in the background all doing the traveling signal with their hands."

To ensure his complaint wasn't viewed as a case of sour grapes, Kerr emphasized players on his team "travel all the time" but that officials are making the game "unfair" by not calling traveling on anyone.

Kerr has not been afraid of calling out referees when he feels it's warranted. He ranted when Stephen Curry fouled out in Game 6 of the NBA Finals against the Cleveland Cavaliers in June, and the NBA fined him $25,000.
