I guess I was wrong about the Celtics. They just proved that even with an unexperienced team with a good young talents can potentialy win against a strong opponent. They just played very well, and I guess we'll gonna see different team in the finals.
They are a very different team from last year's ECF and so is the Cleveland Cavaliers. The Celtics have the advantage here over the Cavaliers because James and some of the new faces of the Cavs needed time to acquaint and jell to the system of coach Tyron Lue.
They have had enough time to get used to each other. A whole season for that and more for a lot of players. They even beat the top seeds in the Toronto Raptors. There are supposed to be no excuses at this point. It is the Conference finals.. not some exhibition game to not "gel" and all. LeBron has come out hard this game but theres only so much they can do by himself. The Celtics are just a better team altogether with players stepping up at the right time. Jayson Tatum and Jaylen Brown showing up big time and cant forget scary terry!

I was wrong about them too

I thought that Celtics can not do much without Kyrie. They are really great composed team. I have so much respect to Brad Stevens and his assistants. And my favorite player last night was Marcus Smart. What an energy that man has, giving so much to the team, especially in defense.
