The Detroit Free Press (Vince Ellis) reports: Amir Johnson has averaged five points and 6.5 rebounds over the last four games, but most importantly, the Pistons are playing their best defense of the season as Johnson’s athleticism, quickness and long arms have been put to good use. And to think, before that four-game stretch, Johnson got no playing time against the Chicago Bulls and had six other DNPs after starting the first seven games of the season. Curry sat Johnson earlier in the season because of inconsistent play and the coach was experimenting with the starting lineup. But it was a rough time for the fourth-year player who the Pistons drafted out of high school in 2005.
