Not to mention Duke's run success in the late 70's was built off Foster getting transfers from other schools, not recruiting.
You keep throwing out Tiny and TMG...but that are only two guys. He has massively underrecruited his mid level players who should be staying 3-4 years and contributing at a higher clip as they get older.
Neysmith, Early, Patillo, Clark, Hardrick, Maze, Allen, Cannon, etc. Those are the type of players you need to stay for their full eligibility to have continued success. Even Kentucky has guys amongst the McDAAs who contribute. You need that experience to carry over...we don't have that.
