Steve Kerr knows a thing or two about good basketball teams, leading the Golden State Warriors to wins in two of the last three NBA Championships. While the Warriors are still the cream of the crop out West, Kerr admitted on Tuesday they "always keep our eyes on the East." And he had a glowing review of what the Celtics are doing right now. "They're all on a string, they play off each other really well, they're really sound and they're motivated," Kerr told the media on Tuesday.
