It's not though. Not even close. Kyrie's a much, much better and more efficient scorer from just about everywhere. Look at one game of the regular season? And ignore his numbers throughout the year and his career both in the regular season and the Playoffs? Yeah, no thanks.
Suggesting the Celtics aren't significantly better with Kyrie is just stupidity, I'm sorry.
Plus it obviously makes them better having both of them available in case one has an off game, or even better, both are on. Because Larkin and Smart are the only other PGs available and Larkin is injured. So you obviously would rather have Kyrie available. Dude is silly for that.
I dont agree with the Cavs not being able to challenge the Celtics at all with Kyrie in the lineup though.
