What happened to Rokas, they not bringing him over anymore?
The long version:
He played for Barcelona, got into a starting role, and won the rising star of the year right of we drafted him. His career looked promising at Barca, but they brought back Ricky Rubio who's beloved over there. Ricky ate into Rokas' minutes and touches, and Rokas' development went stagnant outside of his shooting improving incrementally.
So, Rokas' contract expired with Barca this past offseason, and he came over for Summer League. But he looked roughly the same as last time, and the Knicks' have a PG logjam as it is. He decided to sign with Maccabi Tel Aviv, a good team but not as good as Barcelona. That contract is for three years, which probably means we'll never see him in the NBA, or not for a few years at minimum.
Short version:
Barcelona cut his minutes, his development and the value of his draft rights tanked, and he re-signed a long-term contract overseas. So, he doesn't have much value and won't be an option to bring over for the next couple of years. He'll be fun to watch in FIBA games, but that's probably it.
