You do realize how many offers Adrian had prior to coming to Nebraska, correct? Same can be said for Logan. McCaffrey was also a very highly regarded recruit. Frost is landing guys with the resume.
In high school Adrian received offers from Alabama, Tennessee, Georgia, Arizona State, Ole Miss, Oregon, Cal, Oklahoma, and more. Logan received offers from Ole Miss, Louisville, and had interest from a pile of others, including Alabama and Ohio State, but he refused to talk to anyone after he met Scott Frost. We all know Luke had offers from all the big names but the offers were likely for other positions. Those schools include Colorado, Michigan, UCLA, Ohio State, Washington, Ole Miss, and more. Luke was a project that Scott took a chance on, not a bad evaluation.
He is identifying the same talent as the other big names. Nebraska doesn't have the full supporting cast to make that talent shine yet but to suggest he can't recruit is ridiculous.
