If you spend some time reading on Largs and the people there you will realise Moyes was the best qualified UK coach for the job apart from Ferguson. Largs is world famous and Jose went there just like AVB and Moyes and they are all given advice in groups by the great coaches like SAF personally through the courses. Jose AVB Moyes all know each other well from there this is why relations are so friendly among that crowd. Google also have various links on his philisophy and on paper he sounds more like a young visionary manager.
Because he went to a specific place to get his coaching badges... he was the most qualified? Complete rubbish, also afaik Jose and AVB don't get on. Jose wouldn't give AVB a shot at coaching/assistant manager and left him as a scout for ages before AVB basically told him where to stick his lowly scouting job.
If anything it suggests more than anything the old boys club theory, Moyes knew people and had good networking links from being at Largs, and thus got his shot as Fergie tried to keep it in the family so to speak. A way MANY people get top jobs around the world based on where they've been trained/when to uni/clubs they were in/etc.
How many people have got their badges at largs and WEREN'T any good?
The video on Olympiacos is hilariously awful, it decides that every time, like literally every time a short pass is ignored for a longer pass it is automatically the wrong decision. When I watch the video a large number of the passes it decides are wrong, are the better pass choice. Nothing hugely wrong to passing to someone in not much space, but in a huge portion of the situations on the tape someone has come far too close, has way too many opposition players in and around them and the pass to someone further forward with far fewer opposition players around them is the sensible pass. Someone miss controlling that pass doesn't make the pass choice wrong as was the case on many occasions.
Moyes being friends with top managers is not a credential, Moyes having done his badges at a specific location does not make him a great manager. Great teaching can help make great managers better, but good teaching doesn't automatically mean good students or successful students. Regardless of where he did his badges, we've seen 10 years of him at Everton that screamed in every possible way... not a top manager, not a winner. He was not even slightly the best qualified manager for the job, "can't win" made him one of the least qualified managers in the world.
Now, if Fergie heard about some fresh faced manager who just aced his way through Largs and had been hugely impressive and recommended by the guys running the place and they took a risk on an unproven manager. I'd say that isn't insane, but Moyes wasn't that man, he's spent 10 years NOT winning, losing big games, showing a poor mentality, playing "meh" football and not getting the best out of many of his creative players. You can not lose getting the best out of your defence, but you won't win titles not getting the best out of your attackers. I still don't rate Anichebe, but even he's improved not being under Moyes.
