James Harden spent his offseason in a high profile relationship with Khloe Kardashian and also signed a $200 million contract with Adidas.
Harden was coming off a season in which he improved his defensive commitment and finished second in MVP voting while the Houston Rockets advanced to the Western Conference Finals.
"We know James Harden's a great player. James hasn't played up to his standards," Morey said Wednesday. "I can't point to it. I know he'll turn it around."
The Rockets fired Kevin McHale as head coach this past week.
"One reason people love playing for the Rockets is we worry about what's on the floor," Daryl Morey said. "I don't talk to him about his personal life. (But) I don't think that's a factor at all."
