I just don't get this. His teams generally finish at least above 75% of the others in the league, he's got to have been doing something right and winning games, you're making him sound like Sam Allardyce here when he's only ever been in one relegation scrape and the rest of the time his teams have done well even though they've been handicapped financially.
I'm not saying he spent most of his time in relegation battles, I'm saying that his managerial strengths suit the bottom end of the table more than the top end.
Seasons under Moyes were always a curve. We'd often start terribly, crumble under expectation, but then when things got rough he'd have us grinding out results and then building on that, rarely losing consecutive games, and then climbing to a comfortable league position.
Then expectation would rise for the next season... rinse and repeat.
When we started a season with expectation (same for him at United too) he didn't know what to do. He was more comfortable "taking a knife to a gunfight" than taking a gun to a knifefight. And I stand by that.
