Dirk Nowitzki is still the man in Dallas — and if you didn't get the memo, he'll make sure to remind you one way or another.

The 7-foot German international took the most casual of chances to let young Harrison Barnes know who holds the sheriff badge in the Mavericks organization.

The two went head-to-head in a corner pull-up drill — racking up deuce after deuce until Barnes missed, at which point Nowitzki turned back toward the camera asking “You got that? You got that on tape?” before exclaiming “Nyquil” and casually draining yet another jumper for good measure.

Dirk Nowitzki may have lost some (or most) of his legs, but the 13-time All-Star hasn't forgotten how to make sweet music with his jumper.

One lesson Barnes has taken from this drill — you have to beat the man, before you can be the man.
