I've heard the deadline to get in the draft is tomorrow, Wednesday, at 5 p.m., so there are still a lot of good players that could enter the draft. Last year, I believe that the majority of the top players entered last minute.
That said, from looking at a list of some of the better players in the pool thus far, it seems like the majority of them will be returning players. Not sure if this alludes to the quality in the D-League last year, or that more of the top players are heading overseas. I will try putting together a good list of them soon, hopefully before tomorrow so we can look at what a team is actually returning and maybe start looking at possible allocation players, unless the D-League again beats me to it.
