Bo hired a number of guys with limited experience coaching at the Power-5 level. Papuchis and Ekeler in particular, who had been GAs and made the move from GA to Power-5 position coaches. Ross Els had no experience at the Power-5 level when he was hired. Carl Pelini had no experience at the Power-5 level when he was hired. Rich Fisher had very little Power-5 level experience, all of it as a GA (2 years at Colorado, 2 years at Oklahoma State). John Garrison became offensive line coach after having experience coaching in college only as a coaching intern, and only at Nebraska under Pelini.
Compare this to Banker (nearly 20 years at Power-5 or NFL jobs), Read (17 years at Power-5 or NFL level), Cavanaugh (10 years of Power-5 level experience), and Bray (5 years at Power-5 level). Clearly, the experience level of Riley's buddies is a world apart from the experience level of Pelini's.
Now I get it. You were invested in Bo as a coach, and you're upset that he was fired. In a sense, I see how it must be galling to have him replaced by a coach who just completed a 5-7 record at a PAC-12 outpost. Furthermore, you are probably reacting, in kind, to the acrimonious and bitter verbiage that the anti-Bo contingent spewed on all of us on this forum, over and over again. It grew tiresome and tedious for me, too.
But to make a comparison between Bo's hires and Riley's and trying to group them as much the same, ignores the vast difference in experience. Frankly, trying to compare them as the same makes you look bad. You're a more knowledgable poster and a better person than that. In my opinion, the most telling flaw in Pelini's program was the inexperience of much of his staff and his own inexperience as a head coach. Coaching up the players while coaching up his assistants to be FBS/Power-5 level assistants was just too much for him. Between that and his attitude toward authority and bunker-mentality coaching, along with the Wisconsin game, there was just enough rationale for an athletic director who was not invested in him to fire him.
Regardless, comparing Bo's staff to Riley's (so far) and trying to make them seem the same (in order to take Riley to task) is a flawed argument. It truly is "apples to oranges".
