McCollum is figuring out life in the NBA, and in some ways, training camp will be a way for the Blazers to figure out McCollum, whom they acquired with the No. 10 pick of June’s draft. McCollum played well enough in summer league – averaging averaged 21.0 points, 4.0 rebounds and 3.4 assists – that it seemed he might have a significant role in the Blazers’ rotation this season.

That might have changed Aug. 8, when the Blazers made a late acquisition, signing free agent point guard Mo Williams, a former All-Star who started for Utah last season.

Blazers coach Terry Stotts said Williams will be a key part of his “core” group, which will include starters Damian Lillard, Wesley Matthews, Nicolas Batum, LaMarcus Aldridge and Robin Lopez.

“Core guys aren’t going to change,” Stotts said.
