ND is getting a lot of the guys they are targeting. Also, keep in mind that there is not much difference between a 5* and very highly ranked 4*...see Phil Jurkovic and Derrick Allen.
That said, it is obvious that there needs to be the right fit with 5* players. See Greg Bryant, Max Redfield, Aaron Lynch, Ishaq Williams and Alize Mack (who still has time to live up to the hype, but I'm skeptical it will happen). I think Kelly has learned that fit at ND is more important than star rankings.
