From what I see, Celtics will be the most dominant team in the East next season. Celtics performance to all their meetups against GSW and Rockets last season are closed match and they managed to win each of them. They really gave this top 2 teams in the West a hard time winning. But that is just a season and we all know that teams are different during playoffs especially on what we see in action of GSW and Rockets.

About Toronto Raptors, I still can't see if they will become an Eastern contender even now with Kawhi Leonard but who knows if he can bring changed to this team.

Im also expecting that Philadelphia 76ers will be more of a deadly team as Joel Embiid is eyeing the Season MVP. For this to acquired, he must become more aggressive in getting stats.

And don't forget the Milwaukee Bucks. They managed to bring the series to Game 7 against the Boston Celtics even they are downed by 0-2.

But after this long writing, still I can't see each of them will matched the powerhouse Golden State Warriors or Houston Rockets for now.

Again "for now".
