Again, i'm not defending him in a general sense, but again, you're twisting the facts to make it sound more dramatic. Are results like this only commonplace since he took over? He came in at a time when we'd been dominating global football for decades and ruined it all did he? No. Results like this were commonplace at Everton long before he took over, and have continued after he's been sidelined.
You're making the same basic error/deliberate lie that people do with Moyes all the time. We hadn't won at Arsenal or Chelsea for years before he came and haven't for years after he left, but somehow that all becomes because of the mindset he introduced. It makes no sense. None. It's an embarrassingly childlike view, which doesn't stand up to even the slightest scrutiny. And yet people peddle it all the time as if it's a fact.
What's even worse is that half the people who still believe Kenwright is to blame for our current ills also believe Usmanov is the one pulling the strings. As if he's happy to let Kenwright pick the CEO if he's actually in charge. Just think about that for a minute. Once again, you (not the individual you) have to pick a side. You can't believe that both Usmanov is in charge in the background AND that Kenwright is making the key decisions. It doesn't add up.
