You asked how PJ created a great o-line in year 4 starting with a bare cupboard compared to Scott Frost's year 4 version and I was simply showing the PJ did no such thing. PJ's year 4 o-line would look absolutely no better than Scott's currently does with the amount of pass pro they are asked to do. Yes, PJ ran Ibrahim all over the field with his year 4 O-line which may have made them appear like a good o-line, because undoubtedly they could run block.. That said, that vaunted run blocking still led to a rushing attack that finished some 15 positions behind NU last year. You asked how PJ created such a great o-line in 4 years, and I am arguing that he didn't at all. He simply let allowed them to predominately run block in a poor offensive scheme for an all american caliber running back. Certainly, they didn't pass block at a high level at all.That literally says he had the best run blocking OL in the B1G and 10th in college football...additionally the top graded OLs for last year had Minny at 34th and NU at 94th.

Let Frost build the line. His offense offers an infinitely higher ceiling that PJ's does. He not behind some magical PJ curve O-Line development, rather, he is working on building an 0-Line that support an offense can be competitive with the top teams in the nation, not one that hopes to prove they can occasionally be 5th place in the big10. He may not get there, but nothing is more Nebraska than go big or go home. I don't want to be Minnesota.
