Among MacMahon’s comments: “Not just that Houston wants to, but Houston believes it is a legitimate possibility and that’s not coming out of thin air. James Harden still spends a lot of time in Houston. Spends his summers in Houston. Works out at the Rockets’ facility on a regular basis. It’s a very real possibility. And Harden, by the way, never shot it down. He just said ‘I don’t know where that came from.’”
