Celtics are not challenging and would have got swept the same way that Cleveland got swept even if Kyrie was playing. They have to make some big trades in order for that not to be the case(aka get LeBron or another elite SF).
When will people learn ffs?
It's been clear since Jan that GSW would win just going to playoff mode and if they faced Cleveland in the finals with the nonsense trades they made it was going to get ugly(see my prediction of it going to 5 games max, they were a free throw away from a 5th game).
As much as people want to see anyone else winning, you need to make another super team. If LeBron went to the Spurs/Rockets or Celtics, then maybe I could see them beating GSW. Other than that GSW are winning again. If they went to the rockets they can't trade a star player for them either. So this whole nonsense about LeBron for Harden wouldn't work either. Harden wouldn't go there and LeBron wouldn't want to ruin his finals record by getting knocked out in the WCF
