You all remember that scary moment in the third quarter of Game 1 of the 2008 NBA Finals, Celtics vs. Lakers, when then-teammates Paul Pierce [stats] and Kendrick Perkins collided, sending the Green captain down hard to the paint, writhing in agony.

Cameras in the hallway under the seating bowl showed live images of Pierce being taken by wheelchair into the locker room.

Surely he was done, finished. As Celtics coach Doc Rivers later put it, "Honestly, I thought the worst."
