After Parsons left, former teammate Dwight Howard said his departure “won't affect us at all.” Parsons said the comment didn't bother him, but it was “ridiculous.”
“I know he didn't mean it. He's one of my closest friends,” said Parsons. “He's got to be confident with the Rockets moving forward with or without me there, so I understand where he's coming from. I think it's a ridiculous statement, but at the end of the day, he has to stick up for the Rockets and I don't think he meant it in a bad way and didn't try to bash me at all.”
It's good that Parsons didn't take that comment personally. Howard was clearly just trying to prop up the idea that the Rockets would remain competitive. It wasn't about Parsons, it was about the Rockets.
Also, he was lying.
They're clearly going to miss Parsons. Trevor Ariza is a better defender but a worse scorer and Parsons had familiarity both within the system and with his teammates. The Mavericks aren't necessarily a title contender, and the Rockets aren't left devastated by Parsons' departure. There's even a chance that they could improve overall, with the additions of more defensive personnel, better injury luck and significant continuity they could improve.
But they'll miss Parsons. But that doesn't mean there's any reason for bad blood between Parsons and his former teammates.
