This is coming out of left field and I'm not even saying it's a good idea, but for the sake of stupid message board talk, what about Ben Askren? He's another guy whose credentials would be based almost completely on competition so that's a concern, but those credentials are pretty damn solid.
The cons are obvious and tough to overlook...no head coaching or administrative experience... no guaranteed recruiting ties and no potential to bring in existing recruits from his previous program...no assembled staff to hit the ground running. I'm also not sure if he's ready to be done competing in MMA/grappling.
The pros...4x finalist, 2x champ, 2x Hodge winner, Olympian..had a fun style of wrestling (much like Cael) that would be appealing to this generation of recruits plus the MMA thing could also be a draw for recruits..wrestled for Brian Smith, one of the best program builders of the last 50 years so hopefully picked up a few things...has the type of personality that would appeal to fans and wrestlers.
Hard facts probably say no, so you'd be basing the decision on intangibles and I know we can't afford to whiff if this coaching search comes to fruition. Again, I'm not endorsing it but I think it's intriguing enough for message board talk. Fire away.
