The most recent I cna think of is the 2000 Western Conference Finals, Game 7. Portland being one Game away from the Finals, lead by like, 13 at the end of the 3rd and some how, LA Makes this big Comeback, to win, go to the Finals, and get the first of their 3 back to back to back titles.
Since then, portland was never the same again. Then there was 2004, where Portland almost beat LA, in OT, but Kobe hit a shot to force Double OT. Portland kept it lcose in double OT, and they we're up by 2 with 1 second left. Payton inbounds to kobe, Ruben patterson jumps to block, but Kobe Banked a damn 3, Giving The Lakers a win. In Portland. It was painful.
