Disclaimer: the quote below is NOT an endorsement, per se, of Kiffin. But I think this description of the successful coach in the new 'portal-NIL' era is spot on (my boldface):
But understand this: It’s more than just plucking players from the portal and mixing and matching and winning games. What Kiffin is accomplishing at Ole Miss is part marketer, part carnival barker, and full-time player acquisition and development — the latter being the most critical (and least likely to replicate).
