DNP-clerical error

Portland's C.J. McCollum missed Wednesday's 11-point home loss to the Clippers after he was mistakenly listed as inactive in a lineup gaffe the team called a "clerical error." Coach Terry Stotts signed a lineup sheet that listed McCollum rather than Luis Montero — the name right underneath McCollum's — as inactive.

Stotts took responsibility for the mistake, McCollum called it "unfortunate," and Clippers coach Doc Rivers, whose team has made that error twice in the past year, questioned why there's even an active list. Montero wore street clothes at the game's start and McCollum was in uniform. They switched later in the first half after the error was realized.

A heartfelt gesture

Boston coach Brad Stevens missed Thursday's loss at Chicago so he could return to Indiana to visit former Butler center Andrew Smith, a three-year starter who played on Stevens' Final Four teams in 2010 and '11 and has fought cancer the past two years.

Smith's father, Curt, asked his Twitter followers to "pray for a miracle" and thanked Stevens for visiting his son.

Veteran savvy

Detroit's Stan Van Gundy coached Tayshaun Prince for 23 games at the end of last season and played him nearly 25 minutes a game. So he's not surprised in the least the significant role Prince, even at age 35, has taken with the Wolves alongside Kevin Garentt this season.

"He's a smart guy," Van Gundy said. "He gives them some stability on the floor, good defender, doesn't make mistakes, knows how to play the game. He and Garnett are perfect fits for them with their young guys. It just gives them some stability and experience on the floor. I'm not surprised at all with that."
