Seven series of unfortunate events

As far as probability propositions go, 8-in-174 doesn't sound real hot. But those are the odds facing the 76ers, Pacers, Nuggets, Magic and Spurs after each fell behind 3-1 in their best-of-seven series. In NBA history, 174 other teams have been in that situation in a best-of-seven, and only eight lived to tell about it.
