I don't think England have really suffered with many of the things you mention there, it's just that people always look for some weird connecting link between things so they can put it down to some deep rooted issue. The fact of the matter is England have usually lost to teams who are better/as good as them (often in very close games) because they've never been the very best team in the tournament. This time round they haven't played anyone better/as good as them and so they haven't been knocked out. It's honestly that simple.
The same applies to Everton. For all the hand wringing and talk of bottling and whatever, our recent near misses in cups have come in games against Chelsea, United, City and Liverpool. All teams that would expect to be able to beat us in one off games.
