You still don't seem to understand the difference between being the unquestioned #1 stat black-hole on a team and a #2 - of course Butler's, George's and IT's stats will be superior, in one way or another, to Kyrie's.
Last year was an aberration in IT's career, yet you and many others keep treating it as the norm for a player who is well into his prime. Same goes for Butler and George. Kyrie is yet to even enter his prime years.
Regarding IT, his hip seems to be a chronic issue in the sense that, while he may heal given enough time, it is just a matter of time before the issue reappears again. In short, IT is damaged goods making him, as well as Crowder and Zizic, a throw-in - the trade was really Kyrie for that Nets pick, the players, including IT, were make-weight.
Unlike IT, Kyrie can actually play defense and be very good at it. The problem is he's been inconsistent in his effort but he also had never played on a Brad Stevens team, so time will tell how that goes.
Something to always keep in mind regarding Kyrie, as it was probably the biggest reason why Celtics made this trade - Kyrie, unlike IT, George, Butler, is yet to enter his prime and still developing as a player.
That Brooklyn pick, assuming it ends up being high enough and doesn't turn out to be a bust (two significant assumptions), would yield a difference maker at Kyrie's level in 5-6 years from now. And that's the best-case scenario ...
