The Bleacher Report article above covers this:
"The Sixers want to get out of as much of Granger's contract as possible. Hinkie already pulled off a nifty cir vention of the NBA's salary floor rules, pushing Philly over the threshold at the last possible minute.
While the Pacers have already paid more than half of Granger's $14.02 million salary for 2013-14, his entire hold gets placed on Philly's cap. That means instead of redistributing the unspent money to players currently on the roster—as NBA rules state teams under the floor must do—the owners get to pocket the unspent coin.
Every penny the Sixers save in Granger buyout talks is another in ownership's pocket, as his cap hold remains on the sheet even after a buyout. Joshua Harris, the Sixers' principal owner, isn't known around league circles as a cheap guy, but it has to be easier for him to swallow this terrible roster while making a handsome profit rather than staring at the bottom line."
