I'm not sure that there is such a thing as the WCBB profession. There are professions and roles within, for want of a better word, the WCBB industry - and, you listed a few of them (player, coach, broadcaster, commentator, voting member). As I oft do, I quote my great Aunt Kathryn, who said "where you stand depends upon where you sit". Staley is a head coach, and her stance of "speak no evil" regarding recruiting, reflects that. Burke isn't a coach - in fact, her job as commentator requires her to -*ahem* - comment.
And, whether Dawn or Holly or Margo or whomever likes it or not, for any - ANY - nationally-prominent basketball program, men's or women's, to have an "0-fer" recruiting class, that's at least worthy of comment during a broadcast.
When you add in all the other stuff - high school AA's on roster, disappointing early-season play & results, history of the program, transition from a legendary coach, team chemistry concerns - that just makes recruiting weakness an even greater issue.
Folks are upset that Burke commented on Tennessee's difficulties, on and off the court. That's part of her job. I'd be more concerned if she didn't mention these issues, at least from an integrity standpoint. Public Relations for the University of Tennessee, or any other school, is not her job.
