That is impressive, 3 games above .500 (Lew and beyond) playing primarily against college coaching icons Ron Prince, Bill Callahan, Gene Chizik and Dan Hawkins, and playing 4 whole games against Big 12 North teams that finished in the Top 25 over a 7 year period.
Just as a comparison . . . Terry Allen's teams played 10 games against Final Top 25 North teams over a 5 year period. Allen coached every K-State game against LHC Bill Snyder, every CU game vs Rick Neuheisel/Gary Barnett, and every NU game vs Tom Osborne/Frank Solich (who Nebraska should have never fired).
