I suppose by modern standards 4th, 8th, 6th and an FA Cup final defeat, that record would be seen as relatively successful.
In fact Moyes had a similar enough record and was venerated for it! Different times and a different Everton though.
Moyes was manager in the Blue Bill's "good times" years. Whilst we were expected to compete for the top prizes every year when Colin was manager.
He possibly could've turned it around eventually who knows, it's not as if Howard's second coming as manager was a resounding success.
Colin apparently didn't like upsetting people, he found it hard to drop players while Kendall would have no reservations in making the ruthless decisions and calls.
That's not a criticism at all of Colin btw it was just typical of the gentleman he is. We saw how well promoting from within worked for the neighbours, we tried it ourselves and it just didn't work out in the end sadly.
