I wouldn't be so sure of that depending on who is sponsoring that D league.  There are plenty of 4-5 star prospects who might consider that path because staying eligible for college just isn't an option.  This may have an impact on the overall quality of the NCAA programs, although it wouldn't divert ALL of the talent.  The more powerful programs would simply grow in influence, and the power conferences would benefit while the lesser divisions would suffer.

 

I think a well thought out developmental league with the proper backing would certainly challenge the NCAA.  It won't topple it, but it could give them a run for their money.
