Chandler Parsons and Rick Carlisle are already at odds.
Mavericks owner Mark Cuban made it his mission this summer to land Parsons, which the Rockets looked elsewhere. Cuban, and his new bank of analytics wizards decided Parsons was good enough for them.
After all the recruiting pitches and transition this summer, Parsons came in 20 pounds heavier than he has ever been before.
Parsons thinks that's a good thing, adding muscle to play stronger. His coach doesn't agree with his new three-year, $46 million man.
And the discussion has started to get uncomfortable and incredibly public.
"An increase of 18 to 20 pounds is just too much," Carlisle told ESPN.com. "We talked about it today. We talk about it a lot. He'll get there, but he looked tired out there and a little heavy-legged, and the extra 7 or 8 pounds aren't helping.
"I don't mean to call him out in public or ridicule him, but it's just a fact. He's an important guy for us. We just need him to get to his right conditioning and weight level so he can play his best because we're going to need him to play a lot of minutes over the course of 82 games."
Well, there's not a lot of it yet. But the two side are stating their cases.
Parsons went to Instagram to state his case, showing he isn't exactly overweight with a photo on Saturday.
Carlisle, on the other hand, pointed to the results in Friday's preseason game. Parsons was listed at 6-foot-9 and 215 pounds in Houston but is now reportedly 235.
He went 4-for-12 in the game in 20 minutes.
"He looked tired out there tonight to me, and his shot is short," Carlisle said. "He's working on losing some weight. He's a little bit heavier than he's been. He's up over 230, and we want to see him get down to at least 225. That's a work in progress, and tonight's one of those nights where I think the extra weight was a hindrance."
How will this end?
The best guess is that Parsons will get down under 230. That naturally happens as the grind of the NBA season occurs.
During the offseason, Parsons steered clear of the court most of the time to avoid getting hurt while hunting out his new contract. Instead, he made a concerted effort to bulk up so that potential employers would also see him as a guy who could play strong.
"His opinion of heavy is different than mine," Parsons told ESPN.com. "We kind of go at it every day about it. At the end of the day, I respect his opinion. After training camp, my weight fluctuates. I'll get it down."
