The euphoria over Kentucky point guard Brandon Knight falling into the Detroit Pistons' lap at No. 8 in Thursday night's NBA draft wasn't necessarily shared with other members of a now-crowded backcourt. The Pistons have an important decision to make. Knight's not coming here to sit. He's playing. And those minutes must come from somewhere. Knight's arrival forces the Pistons' hand in choosing either Rip Hamilton or Ben Gordon. One definitely must go, with Knight ordained as the new point guard and Joe Dumars still believing Rodney Stuckey is salvageable with another new coach -- especially now that he's liberated from lead-guard responsibilities. Gordon becomes the more likely sacrifice. An amenable separation seems the best solution for a match that never really had a chance at working. The new collective bargaining agreement — whenever that comes — likely will include a one-time contractual amnesty. Teams can buy out one toxic contract with no salary-cap ramifications. It's similar to what the NHL did when it returned from its seasonlong interruption six years ago; the Wings escaped Derian Hatcher's multiyear deal. Hamilton would be a popular candidate. He has two more years at a $21-million guarantee, and many have soured on him following last season's insurrection. Amnesty also could bring an end to Charlie Villanueva's tenure as a conscientious objector to defense. He's owed $21 million over the next three years.
