Why is that?
Let's assume Ben and Nik reach their potential.
Nik could in theory become a mini Ginobli if he reaches his potential. Excellent on the pick and roll, spot shoot, ball movement. We could always take Ben out earlier, insert Nik, let Nik run a few mins when appropriate as the primary ball handler or at the SF.
Honestly you could get 30/18 at the SG
And Nik to pick up another 10 min between the PG and SF.
But time for those talks is a few years from now, with a whole lot of growing and blessings needed along the way.
