Tim Duncan is the exact same person on the court as he is off, and it is obvious in the new commercial for Black Jack Speed Shop, an auto shop he owns in San Antonio, TX. During a game Duncan banks a shot off the glass and runs back down to the other side of the court, no celebration, no fist pump, just a simple recognition that the shot went

in so he can get back on defense.

As bland as Duncan's style is, it gets the job done and perhaps he's going for the same thing in this commercial.
