He's also never had the chance to recruit with a brand like Penn State behind him (no, Miami is not on that level right now).
If he proves that he can develop talent, he'll do just fine in recruiting. They also have incredible recruiters all over the coaching staff, and no single recruit is a one-coach job. Would it be great if they were bringing in someone who's brought in 5-star kids every year since 2013? Sure. But it's going to be impossible to judge him as a recruiter until we see him recruit as a Penn State coach.
