One has to explain Leicester.
How do you reconcile their meteoric rise with the idea that the league is genuinely very strong? And you have to do that. If Leicester is not a genuinely very strong team (comparable to Europe's finest), then the basic idea suffers (greatly). There are some possible explanations, however:
* They were always this good, or close – but under-performed horribly before Ranieri came in.
* They somehow managed to upgrade to an almost unprecedented degree, either by hiring Ranieri (who then becomes a manager of almost unprecedented genius) or by strengthening otherwise (but how?) - thus going from being genuinely poor-to-mediocre (within the context of the league) to being genuinely top-of-the-line.
* Every team in the league is top-of-the-line. Whether you struggle to avoid relegation or are involved in the title race is a matter of extremely fine margins.
