Celtics' Amir Johnson: Starts at center in preseason opener

Johnson started at power forward and played 15 minutes in Tuesday's 92-89 preseason loss to the 76ers, providing zero points (0-1 FG), two rebounds and one steal.

Analysis:

The Celtics could be without Kelly Olynyk (shoulder) when the regular season starts, so it seems likely that Johnson will have the first crack at a starting role in the frontcourt alongside Al Horford. Johnson had a rough outing Tuesday, accruing four fouls in 15 minutes, but he's a capable rebounder and shot blocker whose presence will likely allow Horford to spend more time on the perimeter.
