I guess, in your opinion, promoting withing an organization is not an option? Well, I disagree. Some programs prefer to maintain the same successful philosophy and continuity and promotion within the ranks is their best option.
Either way it is a never a sure thing. It is difficult to judge. For example, on the one hand, Jen has head coaching experience for years and her records are good, not outstanding but she never had the prestige of UConn to recruit and on the other hand, Shea who has coached for a dozen years under Geno and knows exactly what Geno does everyday and what he wants done every day and knows how the program is run but has never actually run a program.
One thing is certain, neither one is Geno, nor is anyone else. We can discuss this until we are blue in the face, one dumb/wrong decision by the AD and UConn is set back for years. See UConn Football, Tennessee.
