Detroit Pistons' Jerami Grant posterizes Boston Celtics big man Daniel Theis

Jerami Grant is destroying the Boston Celtics.

And he put one Celtic on a poster.

Grant, the Detroit Pistons' big free agency signing in November, continued his hot start as a Piston, driving down the right side and slamming over the 6-foot-8 Daniel Theis, Boston's starting big man.

It was the highlight of the Pistons' big first half, as they try to upset the Celtics (3-2) for the first win of the young season. They led, 27-12, after the first quarter, and upped the lead to 36-15 early in the second quarter.

The Pistons (0-4) and 0-5 Washington Wizards are the league's only winless teams remaining.
