DALLAS -- Holger Geschwindner, the mentor and shot doctor who molded Dirk Nowitzki from a gangly teenager into a top-10 all-time scorer, has arrived for his customary early-season visit.

Geschwindner’s flight from Germany landed on Sunday afternoon. He spent the evening with Nowitzki on the Dallas Mavericks' practice court, putting his prized pupil through a shooting session that is a nightly ritual during Geschwindner’s three-times-per-season visits.

After playing such a critical role in Dirk’s development, couldn’t Geschwindner help 26-year-old Chandler Parsons reach his potential?

“I think we can work on a few things,” said Nowitzki, who cites perimeter shooting as the primary area of Parsons’ game that the Mavs’ new $46 million man can improve significantly.

Can Parsons handle working with a man Nowitzki half-kiddingly calls the “nutty professor"?

“I’m not sure,” Nowitzki said, smiling. “That’ll be a fun first meeting.”

That meeting is expected to happen Monday, when Geschwindner will join the Mavs for the short flight to San Antonio. Perhaps Parsons, a 37-percent career 3-point shooter, will join Geschwindner and Nowitzki in a San Antonio gym Monday night.

“I would love to,” Parsons said when asked about the possibility of working with Geschwindner. “I’m not against working with anyone’s trainer. If there’s a way for me to improve my game, I’m going to be all over it. [Nowitzki] respects him so much, and he’s used him his whole career, so I’ll definitely try to get into those workouts. I’m always looking for ways to improve.”

Parsons wouldn’t be the first of Nowitzki’s teammates to work with Geschwindner. Nowitzki cites Devin Harris and Brandon Bass as two examples of other players Geschwindner has helped.

“Our policy has always been, whoever wants to come, wants to work, feels like he needs some work, we’re here every night,” said Nowitzki, whom Geschwindner would put through unconventional, grueling, Eastern bloc-influenced workouts during Nowitzki's younger years. “He doesn’t say, ‘I’m not practicing with you.’ That was never his philosophy. It’s always, ‘I’m available.’”

Parsons plans to take advantage.
