This seems to me the crux of the issue. Even if all of these players have been rated correctly, very few, if any, will be immediate stars and some/many/most? may not even contribute significantly to the program during the first half year or year after they arrive. All of us know that playing in college is not the same as playing in high school or on the AAU circuit, but it's easy to forget that and designate player A or player B as a "savior" who will quickly turn everything around once she arrives on campus.
Take last year's #1, for example: Lauren Cox is hardly setting the world on fire at Baylor, at least in the games I've watched. That doesn't necessarily mean she was overrated but it does mean that she has a lot to learn to succeed at the college level, and (in this case) it's Mulkey's job to help her do just that. The same was true of Brianna Stewart, who really didn't become the star everyone predicted/expected until the NCAA Tournament her freshman year and then only after being pushed mercilessly by Auriemma (there are videos of this).
Others--maybe Russell and DeShields fit that category or Elizabeth Williams when she was at Duke--never get where expectations predict they should be. That can of course be the fault of the player, but more often (I think) it's equally (or more) the fault of the coaching that's not there. And that's what seems to me to be the major shortcoming of the Lady Vols staff (and not just Holly): they don't seem to be able to help players improve and learn what they need to learn to fulfill whatever potential they may have. And that leads in turn to one disappointing class after another no matter how highly the players are ranked by the various recruiting services.
Your comment about Stewart and Auriemma illustrate perfectly a coach who understands the development needed to play at the College level against great competition and is precisely why these 5 star players at UT now are being classified as over rated ......there has been little development by all the Lady Vol coaches and guess what the Head Coach has complete responsibility for the development !!!!
