Sorry, Jeff, you're too kind to him and/or missing several key points:
1. Moyes put the Fellaini buy-out clause in, so would have known the 'bottom line' as it were.
2. Given the controlling nature of the man, he would, most likely, have got more involved than you suggest, but let's give the benefit of the doubt there.
3. He (rightly) condemned Mark Hughes's unethical attempts to unsettle Joleon Lescott via the press. Then hypocritically did just that for Felli and Leighton Baines.
4. His snidey side-swipes about 'knowing how Everton works' and 'Roberto will need to learn' were small-minded and unnecessary, but the comment about Everton holding back players' careers by fighting to keep them was outrageous and disrespectful.
5. I won't go into the tapping up by SAF or speculating on any cosy pals' arrangement, as it's unproven, but I do resent Moyes's comments about preparing Man U to win every game, and the 'knife to a gunfight' to suggest he was always under-resourced at Everton. (We all know, and a leader's job is to deliver with what he has, not cry-arse about what he thinks he should have.)
6. Then, in the run-up to Weds night, he came out with the back-handed compliment that Everton's team is so well-organised as to not need a manager. If true, how come he only voiced it now Roberto's in charge, unless that was another snidey little put-down betraying a level of churlishness that both surprises and disappoints me?
7. Finally, if reports of his comments about the Everton fans' chants at the match being a 'disgrace' are true (and I'm indifferent whether he embellished his views with fluent Anglo Saxon or not) then he needs to give his head a wobble and reflect back on cause and effect. It was his actions and comments that directly turned the same people who cheered him to the Goodison rafters when he left, despite running down his contract, the Wembley surrenders, Bucharest, Lisbon (x2), 7-1 v. Arsenal, cup debacles and the famous P. 44 w. 0 at the Sky Four.
Sorry, he deserves everything he got, except any (minority) rhyming of Moyes and little boys ('Cum on feel the Noiz') chants. I suspect, when the return fixture comes about you will find yourself in a minority, as he will get loads. And this is not because he left, nor because he wants to sign EFC players and now (must) put Utd first, it's for the reasons above. He dumped on his own legacy.
