Shannon, hands down. Golden had to go, he was unwilling to fire underachieving assistants, but at least you saw that the program was moving forward, he left the program in far better shape than the one he inherited. There's a reason why there was significantly more interest in 2015, than 2010. Golden's organizational skills came in handy, unfortunately he was godawful on gameday, and refused to hire people that could help him overcome that. Miami in 2010 was a nothing job, facilities were in the toilet, Shannon managed to alienate local high schools, despite being a local favorite, and Miami was failing on the field. Despite Al's flaws, at least his hire made a semblance of sense, he had built a solid winner at one of the toughest schools to do that at, and was an up and coming midmajor coach. That said, when it comes to hiring a midmajor guy, it's a mixed bag. For every Urban Meyer, there's ten Al Goldens, or Steve Kragthorpes.
Whaaaaaaaaat?!
How was the program moving forward?! Did you not see the a$$ raping Clemson and mighty UNC dealt to us?
Golden was a terrible recruiter/talent evaluator and kids he didn't offer were seen all over the country making plays at other schools. You don't think Golden alienated local high schools?
At least Shannon fielded a good defense. Only a truly incompetent coach could manage to have a defense ranked in the 100's at The University of Miami, with all the talent we had in our backyard. The offense was ultimately Shannon's demise. They were atrocious and were the main reason we lost that USF game. (which led to Shannon's firing)
The team at least liked Shannon and they played with more aggressiveness and swagger under him. They didn't get their a$$ beat by teams like Pitt. Shannon managed to beat FSU, Oklahoma and a good GT team. We also went toe-to-toe with a Tebow-led UF squad, with a team full of Freshmen.
Yet, the team even without Golden managed to win eight games. They'll win 9-11 this year, with a competent staff. There's no way that Miami would have won that many in Golden's first year, even if someone like Richt was there. Shannon beat an eroding FSU(He was one of the reasons Bowden got sent to the retirement home), OU was beat up to all ****, and was weak that season(8-5) record. Golden beat Georgia Tech often too. The point of the matter is that Golden, despite his glaring flaws, and inability to address them left the program in significantly better shape. Remember, a lot of the facility issues that plagued Coker and Shannon(Neither gave a ****, and didn't make any moves to improve the situation) were addressed by Golden, he not only sold the administration on the importance of improving said facilities, he went out and attempted to fundraise, he sold the donors on the concept, alongside the athletic department. Miami finally started running real camps for recruits, and even though Golden's middling on field results hurt his recruiting, it was a needed addition. Miami may have officially announced the IPF yesterday, but that project was 5 or so years in the making, and Al Golden should get some credit for getting the ball rolling. Unfortunately for Golden, he was unable to combine the few things he did well(Organization), with a compelling on field product.
Now, compare that to Shannon. Shannon's only significant contribution was the concept of academic roadmaps, which was something Coker's lazy behind couldn't be bothered to formulate. Remember the "Admissions is killing us" crap? Identifying and giving marginal student-athletes a workable plan to earn their way in was a big deal, it deepened our talent pool, especially locally.
