Probably. Naz is a weird signing, though. It's not like he's lighting up the league. A SG who is 37%/30%. And it's not like he's a young prospect. He's 24.
DL really failed to put together a decent GLeague team. Doesn't speak well of his ability to a) judge talent and b) the player development program he's touted.
At some point, because of injuries, trades, free agency, having a few decent players developing in the GLeague could become important, especially now that you just can't pluck the best players and sign them to 10-days. Most of the best Gleaguers now have their rights owned by the parent club.
