People underestimate the General Manager requirements of a college head coach. Identifying, acquiring and developing talent are IMO more important than Xs and Os at this level.
K, for example, is only an OK in-game coach, but he's a phenomenal GM. Same for Roy.
Larry Brown, on the other hand, is probably the greatest Xs and Os coach any of us have ever seen, but he can't keep a roster together for more than a season or two.
We're lucky that with the women's program, Geno's the best there's ever been at both aspects of the job.
