Let me sum up this paragraph: "I don't know anything about collegiate athletics, nor do I understand higher education management. However, I want to sound like I do, so I'll throw together this poorly reasoned nonsense and hope the idiots on this board eat it up"
Let's start with the basics, Miami has NEVER emphasized athletics. Why? Because this school is worth a ****, and you can't be a private institution and be managed that way and survive. In fact, most schools worth a **** don't emphasize athletics, because athletics are treated as a separate entity, managed and funded by people called BOOSTERS. The school in most cases have oversight, but there is usually a wall between academia and the athletic department. This is the UNIVERSITY of Miami, not Football Team in Coral Gables, that happens to be associated with some school.
UMiami was able to do something that has NEVER happened in college athletics, and that's win a ton despite never having a long term, legendary coach. This small private institution(That's something I bet that you didn't know, because I'm convinced you've never been on campus, nor even met an actual alum) was able to hit on 4 consecutive coaching hires in a 25 year span. Let that marinate. Most major programs that experience success usually ride one legendary coach for decades. Alabama(Saban/Bryant), OU(Wilkinson, Switzer, Stoops), Penn State (Joe Pa), FSU(Bowden), Clemson(Ford, Dabo), Michigan(Crisler, Bo). Note that even when there's a second coach listed, there is usually a huge gap between those hires. Guess what, those schools with all their resources couldn't manage to follow a great hire with another good hire. Miami literally went from Howard, to Jimmy, to Erickson, to Butch. That's not a bad run, especially when Butch inherited a program falling apart after Erickson stopped giving a F.
Has this athletic department helped itself in the last 20 years with hires? No, because some of them had extremely low success probabilities. That said, Miami will never be managed like Alabama or Clemson, because our fanbase is and will always be trash. They don't donate, barely show up even when times are good and don't provide the community recruiting support that other schools receive. Miami has succeeded DESPITE having some of the worst fans in collegiate athletics, and that's something you can't overcome year in and year out.
