Cant go by comparative scores. I remember the Bulls in 97 had games where they just got by the Bullets then dispatched the rest of their competition in the East into the finals. The 2008 Celtics were pushed to 7 games in the first round against the below .500 Hawks, the 2009 Lakers pushed to 7 games from a Rockets team that had no Yao or Tmac so many examples there.You are anointing the Nets Champions because they are beating a hobbled Celtics team that wasn't that good when they were healthy. The Bucks lit up a healthy Heat team two games in a row. The 76ers are on cruise control against the Wizards. The Heat or Wizards would curb stomp this Celtics team. Beating the Celtics proves nothing.
Sometimes the top seeded team plays down to their competition then elevates their play in the next rd now hopefully I’m wrong about the Nets and they don’t make the Finals.
