Kerr went on KNBR 680 after the Warriors played the Toronto Raptors on Wednesday at Air Canada Centre. The hosts of the radio program were discussing how traveling has regularly gone unpunished in recent years, and Kerr used the opportunity to call out a missed travel call on Raptors All-Star DeMar DeRozan.
"Speaking of which, did you enjoy the DeMar DeRozan foray to the rim last night?" Kerr asked. "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. ... But I can literally put together a blooper reel of plays that are embarrassing travels that are just not called."
The play in question was when DeRozan took four steps to get to the basket and no whistles were blown.
Kerr later said: "It's a case of they have so many things to look at. They are looking at defensive three seconds, they're looking at contact in the lane when people are cutting through. They are looking at the charge and block circle. They are looking at everything except what they should be looking at, which is the basic rule of the game: which is traveling.
"It's a shame. Guys are getting away with murder out there. And fans see it. My favorite is 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. If those people saw it, how come the refs didn't?"
The Warriors beat the Raptors 127-121.
