We are getting really close to the end of regular season. Only a few more games left to be completed. For now Thunder and Cavaliers look really impressive. But I still doubt both of them during playoffs. They were really good last season too but none of them reached the final series.

What do you think about Celtics' chance for a back-to-back championship? They have done really nice during regular season. I think they will find Lakers or Nuggets against themselves in the final series.
Don't sleep on the Cavaliers and Thunder this playoffs. While they may have fallen short in last year's playoffs, they're currently leading their respective conferences for good reason. The Celtics? Of course they remain the title favorites as they're the defending champions with consistent Finals experience. But out West, I don't see the Lakers making noise. My money's on the Warriors to be the team that advances deeper.
Specially the Thunder, they really improved from last year, although from last season, they are the top seed by didn't go all the way to the conference finals as they are young and inexperience.
But this season, it might a difference one as they are more mature now, and obviously the chemistry has grown better.
As for the Warriors, I do agree, they could be the dark horse with Curry still leading them to a very hard and difficult 5th ring.
