There's no precedent in league history for what we saw in the opening days of the NBA's conference semifinals.
Road teams won all four Game 1s for the first time, then came back to win both Eastern Conference Game 2s as well.
That unlikely outcome was particularly notable because of the dominance the East's top two teams enjoyed during the regular season. The Cleveland Cavaliers and Boston Celtics each won 60-plus games, an average of 12 more than the lower-seeded Indiana Pacers and New York Knicks.
As the East series take a day off before resuming Friday -- Indiana and New York take their 2-0 leads into Games 3 and 4 at home -- let's examine what has gone wrong for the favorites and what that tells us about the chances of Boston and Cleveland coming back to reach an East finals matchup that seemed inevitable a week ago.
