I don't know.
I am not the biggest Irving fan, but, that is how he plays. They adjusted to it in Cleveland, but, James was the dictator on the court and he made it work.
Irving was never a fit for this team or Stevens as the philosophy has to adjust to his shooting volume....I guess.
Regardless, the Celtics took on the biggest and best front court in the NBA (Bucks) and a smallish point guard who needs to shoot a lot ends up...being just that.
I also suggest the following.
The Bucks are really good and that Freak beat the spit out of the Celtics and lead his team to victory. Ball movement on offense got smashed up, didn't it?
I suppose we can blame our players and coach, but the Bucks are a better team.
