Please feel free to use the comment section of this thread to post other links you find around the web about the proceedings Thursday night.
P.S. From Mr. Barrett himself, with credit to the Elias Sports Bureau who went through an enormous amount of work to figure this out:
For as long as the NBA has been including play-by-play information as part of its in-game Official Statistics package, neither of those things had happened before: eight points in the final 1.9 seconds (both teams combined) or five points in the final 1.9 seconds by a Blazers player.
