Everton have a much more settled and established team than we had, so on the face of it, they would find it easier to have success more quickly. And unsurprisingly, the Everton fans on here have taken that line.
However, that overlooks the fact that it's not as simple as all that to suddenly change approach with regard to team-building. Everton have been built on a tight budget, with a style of player, play and wage structure to match. You can't suddenly bolt on massive investment to that without causing the kind of disruptive problems that plagued our season.
For example, Everton have great togetherness, but what if they brought in a big name player (or 2, or 3) on big wages? That would cause problems, particularly if said player didn't always put a shift in. I am far from convinced that spending, say, £50m+ this summer would result in Everton doing better...it may, it may not. As our toffee friends have pointed out, spending is no guarantee of success. Say they spent that money, and halfway through the season, were no better off? How would the investors, media, fans react? Would Moyes be under too much pressure? Would the investors seek to dictate transfer policy, or suggest to Moyes that he sign certain types of player? There are lots of unknowns. We have seen the difficulties that can arise, and we are lucky to have very patient and sensible owners who aren't trigger happy.
Add to that the fact that, in my opinion, Everton would have to look to upgrade a number of positions and possibly revamp their style to break into the top 4, and it starts to look tougher than you would think. You start to destroy the togetherness and stability that is the basis of their success. I don't mean that Everton don't play good football, by the way, but certainly they operate at close to 100% capacity and to have success on the big stage I think would require a change in approach. We have already started down that painful road so in a sense, we have a stolen a march on them.
I am sure Moyes would be well capable of leading them to success, but it would not be as easy or quick as you might imagine.
