He just got to their organization. This was his first game with their G-league affiliate. Have no doubt that if he plays well there, they'll bring him up to the Knicks.
And also have no doubt that if he shows he can play there, he will play. Unlike here where Pop went from praising his NBA play one game -- even saying he was earning more minutes -- then promptly sitting his ass for like 12 straight games thereafter, without even garbage time.
I have a feeling the Spurs royally screwed up his situation because he rubbed pop the wrong way.
