The national hit rate is 7% on 3 stars being drafted.

In the same time period (2010-2016 recruits), ND hit on 7% as well. 4 out of 58. One was an OL (Nick Martin). So right at national average.

Wisconsin hit on a whopping 17%.

In the same time period, Clemson had approximately a 14% hit rate (Grady Jarrett, Vic Beasley, Isaiah Simmons the big names).

So one of the gaps between ND and Clemson appears to be selection and/or development of 3 stars.
