If it means Kyrie's extension, then YES.
Chances are we 'll keep Kyrie even without Butler.
But anyway, let's say we make the trade. What happens then with the lux tax?
payroll in 2019-20
Kyrie $32,700,000 (cap projected to be $109 million, 8-year veteran --> 30% of the cap)
Butler $32,700,000 (8-year veteran --> 30% of the cap)
That's $128,223,705 for 4 players!
Not sure whether Wyc and the rest of the owners would love the idea of trading for Butler.
