Source: Houston Rockets guard Austin Rivers opts out of contract

Houston Rockets guard Austin Rivers has decided to opt out of his contract and become an unrestricted free agent, a source told The Undefeated's Marc J. Spears.

After four years with the LA Clippers, Rivers spent short stints with the Wizards and Suns before finding a home with the Rockets. Rivers, 28, settled into a bench role there, averaging 8.8 points in 23.4 minutes per game for Houston last season.

The No. 10 overall pick in the 2012 draft, Rivers never lived up to his billing as a top prospect heading into his rookie year.

But the son of Philadelphia 76ers coach Doc Rivers has turned himself into a capable pick-and-roll ball handler and proved especially useful in Houston as a third option behind James Harden and Russell Westbrook.
