Brohm is a MUCH better X's and O'x coach than Jones. It isn't close. He has good recruiting contacts in UT's target recruiting areas. He played and coached under Petrino but doesn't come with the baggage.
Brown would be a huge risk... OTOH... he does have a win against an SEC West team.
Norvell is probably a bigger risk... but it is hard to be a bigger risk than a coach who has pretty much demonstrated he can't get it done. With that guy... there's pretty much a 100% probability of your program going down hill.
Durkin is a risk as well but he has some of the right influences in his background.
FWIW... I think this list by LWSVOL is more of a reflection of a lack of confidence in the decision makers than anything else. Brohm is the exception in that group IMO. The others are possible up and comers with resumes no better than Jones and Dooley when they were hired.
