Miami job is good...but it's not top 10-20 like UGA and USC. Miami does not have an on campus stadium. They do not have the athletic budget to pay assistants (and the head job maxes out around $3 million, which is a nice income...but a great coach can get 33% or more than that at a better program. Hell, Houston offered $3 million to keep Herman!). They also play home games in front of around 20,000 (or less) fans for the average game....then when FSU or another big program comes to town, half the stadium is pulling for the other team. And "great" coach that goes to Miami will leave (for the NFL or another big time program). Miami is a good job....just not great.
UCF? That's laughable. It's a great job for a 1AA coach to move up to D1 or a "hot" assistant to cut his teeth and move on. O'Leary was perfect there because he was old and damaged goods....it was his last stop. So, maybe a Richt or Mack Brown type? (but Richt could probably land a better job). They are looking at UF's DC right now (Collins....they also interviewed UF's Co-DC, Randy Shannon), among others.
