Like Cajun T mentioned Roberts has a track record similar to Hud. The systems we run are very similar to what Roberts has done how whole career so the talent is in place to take off from the beginning.
If you go after a coordinator who know how he will adjust to being a HC. When you hire someone with the HC experience your not learning on the job.
For the record I'm not against going after an asst from an FBS program. This next hire, whenever it happens, will be the biggest in Cajuns history so you have to make sure you get the right guy.
