AUBURN HILLS, Mich. (AP) - Joe Dumars and the Detroit Pistons have been waiting a while for this offseason - and it showed. The Pistons have finally been able to give their roster a significant makeover, adding Josh Smith, Chauncey Billups and Italian star Luigi Datome. It remains to be seen how much the team will improve, but for the first time in a while, there's a bit of a buzz surrounding this struggling franchise. After four straight seasons without a playoff berth, Detroit entered the offseason with plenty of space under the salary cap. Dumars, the general manager, said this week he's accomplished what he wanted to via free agency.
