That's why there's been no hiring. Barta is still waiting. He may be interviewing for Plans B & C, but his targets are still coaching their teams.
The reason no one has bee hired is that the search committee wasn't even named until the weekend, and have barely had time to settle in. It is not a strong committee, and Barta should be able to influence it as he desires--except for two notable possible problems for him.
(1) The search committee, like the athletic board & the presidential committee on athletics are roughly half female, even more feminine gender among the key players (faculty advisor, chairman of the Prez committee, are late middle-age female senior faculty--out of the Bluder Bunch & tilted toward UIHC staff, including physical & occupational therapy & the "health-nut" crowd who view alcohol, fast-food, etc as moral issues).
Key possible major complication for Barta: much of the search committee, and the administration officials and activists with whom they are closely associated are Sally Mason loyalists, her views (IF she plans to play a role) will have vastly more weight to the committee than Barta himself. Of course, that is a huge IF, and she has yet to tip her hand.
(2) We don't know the full extent of the attitude that in replacing Alford Barta (post Skorton,pre-Mason & especially post-Ann Rhodes) was allowed the latitude of pretty much making his own search and choosing the new coach himself without much oversight from the administration or having to contend with active search committee members--and the result was not a great success. On the other hand, Bowlsby could not and did not control the search process in finding the successor to Hayden Fry; indeed his own choice was vetoed, and powerful administrators on the committee (Ann Rhodes, Phil Jones) prevailed and their guy, Ferentz, ended up being the guy that a reluctant Bowlsby named the new coach--"meddling" that resulted in the selection of an exceptional coach and a source of immense prestige to the university (as seen from Old Capitol).
We know this much: the selection of a search committee by President Mason, with her people in key roles, clearly suggests that she intends the search process to replace Lickliter to be more like that to replace Fry than the one to replace Alford.
Footnote: Probably pays to bear in mind the last, significant remarks of Barta at his press conference. After strangely listing Lickliter-like qualities that he would look for in the new coach, he ended with an emphasis on how the new guy would have to have Iowa & U of Iowa "values"--meaning that Mason has set one essential requirement: no one with a dubious background, no one associated with scandals or violations at other programs, make certain no more Alford-Pierce blackeyes are suffered by the University (we want to win; but even more we want to be respected as a university that does things the right way).
The chances of guys like Barbee, Drew, Stallings are less because of this mandate, whether it fair, whether it is undeserved. Barta could choose another guy who doens't win enough--and still survive; what he cannot afford is to pick a guy who fails the Mason mandate.
