I was hoping for Kyle Anderson, but I'm good with this deal. Hernangomez is likely a better option at the 4 than Grant. If Grant beats him out, that means he's taken a real step forward, which is fine too.
Juancho is also a larger expiring than Dunn, and thus can bring back a bigger salary/aggregate to bring back a bigger salary if such a deal arises. And who knows, maybe he'll fit in great and be a viable rotation player at sub-MLE money for next season.
I feel we're probably done with moves for a bit, although I'm now going to vote for cutting Parker and bringing back IT on a 1-year minimum. Balances the roster better, saves $500lk, and hopefully breaks the curse that the Kyrie trade set upon the franchise.
