AUBURN HILLS, Mich. — If Paul Pierce is concerned about his recent shooting struggles, he isn’t showing it. The Celtics’ leading scorer is shooting 35.3 percent from the field in his past four games, missing 16 of 19 3-point attempts.

The Celtics experienced trouble scoring in losses to New Orleans and Chicago, relying on staunch defense to stay competitive. Pierce said he doesn’t consider his recent skid a legitimate slump.
