Fair enough, though I also take exception with an assertion you made in the previous post :
United's executive board (the real power brokers at the club) has exactly zero people with background knowledge of football. That is not robust at all as it pertains to sporting decision making. The board will trust the non-executive directors with the footballing side of things, and if you look at that :
Sir Alex Ferguson : The most important man in the history of United, but he's nearing 75 years of age, and there will be a natural dissonance with his grasp on the way football is headed. Might sound weird right now, but between him becoming progressively mellow, focusing on his books and seminars, and distancing himself from the actual bare bones running of a football club, Fergie's decision making will deteriorate, and he will be more romantically inclined to favor a son-like figure in Giggs, than rationally weigh all the possible outcomes.
Sir Bobby Charlton : The most important player in the history of United, but he's nearing 80 years of age, and like Fergie, he will be captivated by the idea of Ryan Giggs as the United manager, a player who succeeded in his legacy, becoming the manager of United. He also championed the cause of David Moyes previously, while coming up with platitudes their pertained more towards his grasp of the culture, old school values, 'blue collar' work ethic, and other tangential traits; rather than footballing achievements, so we should keep the objectivity (or lack thereof) displayed previously in perspective.
David Gill : We know that he wasn't the biggest fan of David Moyes to begin with, but was kept in check by people with greater decision making prowess. As United's ex-CEO, someone with a deep understanding of major business decisions, and a finance man, he is arguably the most objective one out of the three. But again, will his input be overruled? And given his involved with the FIFA and UEFA Executive Committee, and the FA, how likely is he to immerse himself when the current managers needs replacing?
So really, if you look at it in greater detail, we're not really that robust to be honest, especially when it comes to sporting decisions of this scale. We're not like Bayern Munich who previously had Uli Hoeneß, Andreas Jung, Karl-Heinz Rummenigge, Matthias Sammer; or Ajax with Dirk Schoenaker, Tonny Slott, Edwin van der Sar, Marc Overmars when it comes to football experience, and being up to date with the upper echelons of European football. The owners and executive board members know next to nothing about football, and will likely trust Fergie and Sir Bobby again, and them giving in to their romantic instincts might backfire spectacularly, as happened with the Moyes appointment. The most important person in all of this might just be Ed Woodward, the final decision will likely be his, and one hopes that he considers the appointment on the basis of merit, as it should be. If Giggs' CV stacks up against the likely candidates, then ok, give him the job, though with Guardiola leaving Bayern in the near future, and Ancelotti still looking for a job, that might be extremely unlikely, if not downright impossible.
