Houston Rockets general manager Daryl Morey knows adding Ty Lawson is a risky move. He believes the possible reward is worth that risk. Lawson was acquired in a trade with the Denver Nuggets on Monday, giving the Rockets needed depth at point guard, though he is currently dealing with off-court issues. He entered a 30-day residential treatment program last week after his second DUI arrest. Morey noted there are always risks with players, whether it’s concerns like Lawson’s or with injuries or other issues. “When you’re trying to be the best team out of 30 you’ve got to risk all over the place,” he said. The Nuggets receive a lottery protected first-round pick in 2016 and cash considerations along with Nick Johnson, Kostas Papanikolaou, Pablo Prigioni and Joey Dorsey in the deal that also sends a 2017 second-round pick to Houston. – AP
