Chauncey Billups returned to Detroit Pistons practice today, and while not ready to start playing, it isn't starting that concerns him.

It's finishing.

The Detroit Pistons guard probably lost his starting job to Kentavious Caldwell-Pope during his ongoing injury absence, but said he sees a void in fourth-quarter performances that he can address.

With his return growing closer, Billups already is floating that suggestion.

The Pistons have the NBA's second-worst fourth-quarter average scoring margin, minus-2.5 points, ahead of only Charlotte's minus-3.7.

"I think we've just got to get a lot better in the fourth quarter," Billups said. "We could have probably four more wins if we could just be steady in the fourth -- not great, just steady.

"I hate it because I know that that's one of the areas where I can really help us. That issue's not going to go away. Experience is the best teacher, so you've just got to kind of keep going through it."

Billups started the Pistons' first seven games before knee tendinitis sidelined him.

The Pistons (9-10) are 7-5 since then, and while Billups said they have grown more cohesive since he last played on Nov. 12 at Golden State, the uneven fourth-quarter play remains troublesome.

Much of that is attributable to guards Brandon Jennings and Rodney Stuckey missing large portions of training camp, which showed early in the regular season.
