What's wrong with the Celtics?

NEW YORK -- I am not a Celtics fan, which put me in the minority Sunday afternoon at Madison Square Garden (where the loudest cheers were for, in order: Kevin Garnett's game-winning shot, Will Ferrell's appearance on the video board, the Knicks' gritty effort).

But all those folks cheering for Boston (there were so many of them, they could have nicknamed MSG "The Greenhouse" instead of "The Mecca of Basketball") had to have walked away with as much frustration as enthusiasm after watching the Celtics squeak past the New York Knicks 107-105 in overtime.
