Kevin Stallings isn't the most impressive hire, in fact, I think they should've went with a better recruiter or at least tried harder to get one. That said, it isn't an unmitigated disaster. He's done fine at Vanderbilt.
I do find the reaction to this hire to be hilarious though. Like, he's a coach that has done pretty decently throughout his career, but the way Pitt fans have reacted you'd think they'd have hired me to be their head coach or something.
