It's a good deal for the cavaliers as finally they found a point guard that is a real passer, also, adding Jae Crowder will just strengthen
their 3 point shooting. Well, I hope Irving will help the celtics improve, he is a superstar and I know he can do it.

Dont really think IT brings a lot in terms of playmaking. He's really only a scorer . However, Drose  can be utilised as a passer now that he can come of the bench

I'm not sure though. It is really tempting if you're offered a player of kyrie's caliber but boston just came from a really good run last season with the core that they have now. I'm not sure how this trade is going to work out for them but definitely the cavs will benefit highly from this.

I just don't get what path the Boston Celtics want to take because they gave up the 1st pick and not drafting Markelle Fultz in what I thought including the fans of the Celtics that Isaiah Thomas was their long term Star Point Guard and now they are trading him away for Kyrie Irving along with Jae Crowder and a 1st Round pick from Brooklyn. I really hope they do know what path they are going because acquiring Gordon Hayward would be a waste for the team.

You forgot that the Cavs got a first round pick on next year's draft too. So the Kyrie trade did pay them off well.

I really thought thathat Kyrie Irving would have gotten over his pride and stayed at the team, I don't know how the move to Boston Celtics is going to affect his career in total. I really don't want the Golden State Warriors to win the NBA championship next season and with Kyrie gone I doubt the Cavaliers can challenge properly.

The thing is Kyrie is just 25. The kid is just entering his prime. It's pretty reasonable to build a franchise around him.

It looks like they didn't count on Thomas on long term, but as you say Kyrie is 25 years old and has at least 5 great seasons to play. To build a franchise around him is good thing, he is amazing player.
On the other side, Cleveland will be stronger team with those three players but I think that Thomas will be in same situation as Kyrie was. He is a scoring machine and playing with Lebron will suffocate him. Instead of scoring 30+ points per game he will have to settle on 10+ but will be closer to a championship title.

Here's my opinion about the final deal of the Kyrie Irving trade;

Who won the deal for me? First of all, we can't say 100% what those players involved in the trade will contribute to their respective team this upcoming season. Maybe there will be a surprises. For me, the winner of the trade is Cleveland Cavaliers.

Why?

-Isiah Thomas plays very well last season. He is one of the reason why Celtics clinched the Eastern Conference top spot. Couldn't imagined Celtics gave up this guy. Include also the contribution of Jae Crowder in terms of defense and ability to dominate the make points in the paint. Cavaliers need this type of guys in case of Lebron dissappearance in the upcoming seasons.

-Cavaliers also get the rights to acquired the Brooklyn Nets' 2018 unprotected first-round pick.

-I see, it will be a good blend as IT and Lebron have different playing style. Plus the fact that they also enhance their Big Man's lineup which Cavs really needs.

The downside; IT will be free agent next season and I don't see he will accept a max contract to the Cavaliers. Lebron also not sure if he will stay at the Cavs.
