No doubt the Pistons miss Andre Drummond, who will miss his 18th game tonight against the Trail Blazers. The Pistons miss Brandon Knight, who likely will sit out his second straight game with a severely sprained left ankle. But as the Pistons try to snap a seven-game losing streak, it's obvious they have struggled without Tayshaun Prince. Not many would dare say the Pistons made a mistake in trading the longtime veteran to Memphis in a three-way deal that brought Jose Calderon and future financial flexibility. But as the defense has become a sieve recently, Prince's communication and know-how have been missed.
