Watch Jabari Parker throw it down — then hit head on rim

I have this problem all the time.

During Saturday night’s preseason game, the Bucks’ Jabari Parker got the ball and had a straight-line drive to the basket, which he wisely took.

Then he threw it down with authority. Two hand dunk.

Then he hit his head on the rim.

Damn.

Parker had 21 points in 24 minutes on the night.
