Have no fear: Dirk's mentor Holger is here

DALLAS – How does Dirk Nowitzki work his way out of a slump? Some sessions with personal shot doctor and longtime mentor Holger Geschwindner tend to help.

There’s no better time than now for Geschwindner, who accompanied Nowitzki to the American Airlines Center before Tuesday night’s game against the Oklahoma City Thunder, to arrive in Dallas from Germany.

Nowitzki is fighting through one of his worst funks of the season, shooting just 41 percent from the floor and 30.8 percent from 3-point range over the last five games. He’s coming off one of the worst shooting nights of his career, a 10-point, 2-of-12 outing in Sunday’s overtime loss to the Brooklyn Nets.

Geschwindner, who was here during Nowitzki’s hottest stretch of the season in February, typically makes three visits per season: one early, one midseason and one late, sticking around through the Mavs’ playoff run. This visit is a little earlier than normal. It’s not known if it was planned that way with the Mavs needing to make a push to make the playoffs or bumped up a bit due to Nowitzki’s recent struggles.

There’s no doubt, however, that the gray-haired guy in a plaid shirt and leather jacket is a welcome sight for the Mavs’ star.
