The Warriors have no doubt the popularity of the championship, as long as the current Durant + Curry + Thompson + Green is healthy, then the Warriors will always be the biggest favourite to win!
The Houston Rockets can only hope to win a dream if they want to win!
Don't forget another great player in their team, the new one, Cousin. Some say that he is not that great player since he just got from the injury but even though he is, he can still help his team greatly even if he is not always in the court. Houston might their chance but it depends on how their newly built team will do in the new season. There are a lot of great teams to look out for and I don't know what will happen to Kahwi.
Having Cousins put a lot of depth on Golden State right now. Golden State team is built not around centers, that's why they traded Bogut as far as I can remember. But having Cousins will give them another options, if the outside shot is not working, then they have have Cousins works on the painted area to score or even a bait and throw passes outside of 3's.
This is the reason why GSW's lineup is more dangerous that their lineup last year because of getting Cousins. Warriors doesn't have good centers if we can see but they have lots of shooters. Looney and McGee is an average centers and they are nothing against the other centers but the addition of Cousins that can shoot threes and at the same time, can pass and can dominate the paint makes them the choice of the crowd as the champion of 2019 NBA season. If they will have a good chemistry next season, they have the higher chance to win again.
At the same time, GSW will be more prone to technical fouls because GSW has the most technical fouls and ejection last season and we
know that Cousins is prone to technical fouls too. Hahaha. GSW needs to control Cousins and I think him and Green should somewhat check their emotions. Anyways, sometimes this players are just carried away specially if the game is close. Green though is more mature if he can be a good role model for Cousins then it will really be a bonus for the team.
