He’s not a surefire top 15 player. I have (in no particular order)
Lebron
Kawhi
Durant
Giannis
PG13
Curry
Westbrook
Harden
CP3
Wall
Butler
Davis
Cousins
Towns
All above him. That’s 14 players. So for the 15th spot I think he’s fighting with Lillard, who I think are really similar players. But that’s not even mentioning Derozan, Hayward, Griffin, and Gobert who I could potentially see someone taking over Kyrie.
Edit: Add in Klay and Draymond who are guys you could potentially argue for over Kyrie.
Cousins - was on bad Kings teams and NO got worse post-trade while the Kings got better. Can't put him above an NBA champ alpha who was all star game MVP at 21.
Butler - He's a very good 2 way player but if he doesn't put up 25-5-5 on Minny and lead them to the WCF, then he can't do what Kyrie did this year and isn't better either. Don't believe he ever made the ECF in a weak East even on his pretty [dang] stacked Bulls teams.
Towns - if you plan on keeping Kyrie out for his poor D then you'll have to keep Towns out too. Towns hasn't even played on a .500 team yet. So no for him.
Giannis - probably will pass Kyrie in the next 2-3 years but so far he's had only one year of monster stats and never gotten out of the first round. Nope.
PG13 - He had him in the past but PG13 put up worse stats as the undisputed alpha on the 7th seed in a crap conference. When he was a top 8-10 player he had an insane amount of help. Can't say he's clearly better until he regains his old form.
CP3 - I love CP3 but he's pretty old now and we're comparing an NBA champ who might be the most clutch player in the league to a guy who has been amazing but has choked in the playoffs and never been to a conference finals. I'd say this is debatable in 2017-18.
None of the guys not on your official list are better than Kyrie.
If these revisions are accepted, that puts Kyrie in the top 9-10. If you wanna say there are only 5-6 superstars then no he isn't, but he's absolutely a franchise guy as a top 10 player in a league with 30 teams.
