Well, the best thing would be to get the knicks history dvd, which includes those 2 games fully, plus another 6 great ones (first title, king's game against thomas' pistons, etc..)
if you just want clips, you can go to [Only registered and activated users can see links. ] and search them. you can find both lj's 4 point play and H20's buzzer beater.
btw, welcome aboard!
