The walk was long.

After staying on the floor for a few extra seconds in disbelief over his sixth foul, and then expressing his disbelief to referee Joe Crawford with a hurt expression as he appeared to be on the verge of tears, Antoine Walker walked diagonally back across the parquet to the Celtics bench.

With 2:51 left in what turned out to be the first of two overtimes, the Celtics co-captain's season was over. It's amazing how much thought can go into a walk across three-quarters of a basketball court.
