Unrelated to Raps/Pistons itself but relevant to 1st-round matchup and maybe influenced Raps/Pistons matchup:
If the league didn't change the formatting rules for a division champ to hold a top 4 seed at best, Orlando Magic (division champions) would have been the #4 seed while Boston is the #5 seed (with home-court advantage). Remember in 2012 when the Celtics had the 4th seed due to winning the division while Atlanta had the better record, but Atlanta had home-court advantage? How times have changed.
So the Celtics would've had to face Orlando in Round 1, who swept Boston this year.
