Will Bynum (foot) is out again for Sunday's game vs. the Celtics. In addition to giving Peyton Siva a foothold in the rotation, Bynum's absence means that Rodney Stuckey will spend some time as a backup PG. With the Celtics' backcourt already running on fumes without Rajon Rondo and Avery Bradley, guys like Brandon Jennings and Stuckey have a golden opportunity to step up.
