College football is not static. Houston is in a bigger city than Miami and Texas is about as football crazy at Florida. Miami does have the edge in being almost 340 miles from UF, while Houston is only 165 miles from UTx. Still the roads are better to UF making the drive time not as different as the miles.
So the Houston job is very attractive to someone who think they can build it up. And just off the top of my head, they could play off of Miami and call themselves "Dis U" or "Our U" rather than "Da U." Now the coach to go there would need to have a fun style to build up the program as Holgerson does. The school would need to commit and the coach would need to rally the community, but I see no reason you could not build a top program at U of Houston.
Miami did this despite changing coaches a lot. That take a bit of luck. I think the FSU or UNLV in basketball style of getting a coach and keeping him several decades is the safer way to go.
