Division I is such a wide net to cast. There's 351 D1 basketball school. The talent level at top tier schools like KU or Duke is higher than all but the very best Euroleague teams. Well even then the talent level is probably higher at the schools, but the development level and age (size/strength) goes against them. The other end is bottom of the barrel D1 programs are filled with guys that are never gonna play professional ball at any level.
With that much variance there's no real way to answer the question definitively. But I would say that anyone good enough to get real minutes for a school that's consistently top50ish in D1 is probably good enough to at least make a roster in just about any league.
