The frustrations for Celtics fans stem largely from the fact that because Boston brought back much of its core and added an All-Star talent in Horford, the expectation was that this team would hit the ground running. That hasn’t happened — in large part because of injuries like the concussion that sidelined Horford for nine games — but the question remains how good this Celtics team can be now that it has all its horses.

These next two weeks could go a long way toward determining that. Stevens is encouraged by the recent progress but he understands his team has strides to make. Fortunately for his players, Stevens always keeps his focus on where the team wants to be as opposed to where it currently stands.
