How can the Pistons play well with Iverson?

Whats going on with the Pistons? they SUCK. I thought Iverson was going to make this team just a little bit better, but he aint doin S H I T. He's only averaging about 18 points. Rodney stuckey is the new star in Detroit, but thats what they brought Iverson to Mo Town for. To give Detroit that star power. I dont know what is going on with the pistons. They lose to weak teams like the timberwolves and the bobcats and the pacers ( Danny Granger is a BEAST), but won againts the Lakers, Spurs, & Cavaliers. I dont like the Pistons anymore. They should have kept Billups.
