For me the killer was hiring Shannon. Shannon was simply not qualified and was a mistake. It set the program back tremendously, and Golden was just a continuation of that mediocrity. UM was coming off a monster run when Coker was let go. He obviously was not up to the task of maintaining an elite program. But instead of going out and hiring a top gun coach, at a time when UM was paying pretty well, someone like Gary Patterson, who would have been a MONSTER at Miami, and could have been had back then, they went with the cheap and easy pick. Yes he was a former Cane, and had the heart warming "hard knock life" story and all that, but there was NOTHING Shannon had ever exhibited to suggest he was HC material. Even as a DC, he was reclusive, weird with the media, his recruiting was questionable, he had no real strong pedigree beyond bouncing around a few places as a position coach. Wasn't like he had been Jimmy Johnson's right hand man, or learned at the right hand of a top coach.
They gambled on Shannon, hoping that it was all a matter of a local/Miami former Cane who could keep the local recruits home and it would all work out. Instead Shannon had no ability to recruit quality assistants, was lost as an HC, his recruiting beyond his one big class was uneven and got progressively worse, and it just dug us deeper and deeper into the hole. By the time he was canned, UM had been out of the "Elite Spotlight" for so long, that getting a big fish to bite on the job was probably a long shot, so they had to go with the "up and coming young HC" route.
All told Golden seemed on paper to be a decent choice. Obviously he has failed miserably. But not having replaced Coker with a top notch HC to keep the program running strong is what really dug the hole. Golden has been a total continuation of the Shannon mess. I mean its been almost identical in terms of results. Only difference is Golden is better with the media, in public and speaking, and the Shapiro mess got him a deeper extension that has obviously made it harder to can him.
