There's a trend at work here, and Murray has been a huge part of it. The Hawks have been absolutely killing opponents in second quarters, when Murray and Zaza Pachulia normally play nearly the entire frame, and it has been the main reason the Hawks won all seven games on their just-completed homestand.
It's an unusual arrangement because the Hawks are down to a seven-man rotation in Marvin Williams' absence -- Acie Law and Mario West see occasional cameos, but basically Pachulia soaks up all the backup frontcourt minutes, and Murray does the same on the perimeter.
He also calls out that Al and Zaza on the court together are too physical for other teams' 2nd units. Flip value is acknowledged by most everyone, but Zaza gets mixed reviews on this board. Perhaps he's more valuable than original thought if used at the right times?
