It took just one game back for Pistons coach Lawrence Frank to lament that “anything they wanted, they got.” It came after Detroit allowed 119 points to the Brooklyn Nets.

Really, the Pistons’ defensive breakdowns are nothing new. Detroit has been allowing opponents to get anything they want for about a month and a half now.

On Feb. 7, the Pistons ranked 19th in the NBA by allowing 103.5 points per 100 possessions.

Since Feb. 8, the Pistons have allowed 112.1 points per 100 possessions, a mark that ranks last in the league.

So what changed?

Anyone who watches games will say Andre Drummond. Sentimentalists who recall his four all-defensive second-team selections will say Tayshaun Prince.

And they’d both be right.

The super-athletic Drummond already defends the rim better than any Piston since Amir Johnson, and with quick feet, Drummond guards well in space, even though he doesn’t always know where to go. But because of a back injury, he hasn’t played at all during the skid.

Prince, at his peak, defended better than any of this year's Pistons ever have, and after a couple of lackluster years, his defensive effectiveness has at least somewhat rebounded. But Prince was traded to the Memphis Grizzlies, so he hasn’t played at all during this stretch, either.
