No.
While close, none of them are top tier talents in the NBA. They are upper 2nd tier.
Some that I consider top tier currently are,
James Harden
Russell Westbrook
John Wall
LeBron James
Kevin Durant
Anthony Davis
Other recent top tier talents
Paul Pierce
Kevin Garnett
Shaquille O'Neal
Kobe Bryant
Dwayne Wade
I don't pretend that these lists are complete, just examples based on my opinion.
I do think our current roster is one of the deepest with high level talents ever. Just not top tier of the NBA talent.
