I have decided to annoy you. Congratulations. Rather than scream "Bowdenheisel!"© 500 times, I am going to suggest other coaches SMU is apparently not going to consider. Unlike Bowdenheisel (tm), I am going to suggest coaches that other schools that haven't been looking for coaches as long as SMU are considering.
Larry Fedora (OC Okie State)
Larry Fedora is a man and he is 40 (actually 45, I think). He is also a very well respected offensive coordinator and recruiter. Some will tell you he is a genius and if they don't, he will tell you he is a genius. Before becoming the OC at OSU, he was Zook's OC at Florida and Zook offered him the same job at Illinois but Fedora took the offer at OSU. He is a Texas native and went to Austin College. He also coached briefly in the HS ranks in Garland, Texas. Plus, I think he has a cool name.
He is expected to be named the HC at Southern Mississippi any day now. They are arguing over his budget for assistant coaches. SMU could have him if they acted assertively.
But, alas, we aren't looking at first-time head coaches. Personally, I believe that sometimes it is better to find a good coach yourself than overpay to hire a coach away from somewhere else.
