All the championship experience in the world isn't going to help the Boston Celtics Friday night if their legs start getting heavy again.
They may be running out of gas.
The Celtics still lead this peak-and-valley ride of an Eastern Conference final against the Orlando Magic, 3-2, but the wear and tear of a long season, coupled with the physical pounding of three playoff series, has begun to show. The momentum has shifted dramatically.
If the Celtics can't deliver their knockout punch early tonight in Game 6, it likely won't ever come. A potential Game 7 is slated for Sunday in Orlando.
