You're talking about degrees of extremity here not that the plan was deviated from. Fulham was Moyes' nadir because he was so out of his depth it didn't even come to mind to try and do anything else. All season long we drummed the same football to varying degree, probably mostly because Moyes didn't know how to do anything else.
The style of football was un-befitting for us and that's what made it so loathsome for our fanbase - we were in shock of going from the force we were under Fergie to what Moyes' terrible football turned us into, but again, relatively is a vital component in this assessment - the sheer shock of being what we were to what he turned us into will sour some beyond objectivity. In Mourinho's case, he has a squad that costs a fortune, has no idea what to do with them, cannot coach them and on top of that, has no balls to attack the opposition. It's very easy to mentally tune out of our games because of that.
It just baffles me when people say we're almost as bad as LVG/Moyes now, because on a scale of relativity, we've long since reached that point when resources are thrown into the equation.
