That was... I mean...
I think that may be as big a shot as Robert Horry's shot in Game 4 of the 2002 Western Conference Finals!
Allow me to explain:
The Lakers had a 16 point lead in Game 5 in San Antonio at the SBC Center 
(where they had never won a playoff game). 
The Spurs came back and eventually took a 3 point lead. The Lakers battled that back and took a 1 point lead with 11 seconds left on a Kobe Bryant jumper. The Spurs got the ball, got it to Tim Duncan with 5 seconds left and Duncan hit an out-of-control leaning shot with Shaq all over him and .4 seconds left on the clock. After about 3 timeouts, the Lakers inbounded it to Derek Fisher, of all people, who spun and released it a milisecond before the buzzer expired and when it went in the Lakers ended up winning 74-73 (click for video). Now THAT was a finish! The Lakers got so so SO lucky in this game to get away with the win after that kind of collapse.
By the way, it was exactly one year ago to the day that the Lakers lost Game 5 to the Spurs in San Antonio when Robert Horry missed a last second shot (here's a link to my entry on that game). But thankfully things are different this year (so far at least), and this time the last second game winning shot dropped for LA. Eerily enough, it was a year ago Saturday that the Lakers were eliminated by the Spurs in Game 6 at Staples Center. This Saturday the Lakers have a chance to return the favor and eliminate the Spurs in Game 6 at Staples Center! :grin
