I'll go you one better, which I read about in Marvel Comics: The Untold Story. According the Whilce Portacio, he and Jim Lee replaced Chris Claremont as the X-Men plotters because the editor "hated everything that Chris said." That's right, Claremont was actually demoted to scripter because the editor thought that he knew better than a guy who turned the X-Men from a cancelled title into the best selling franchise and a multimedia juggernaut.
That editor, of course, was Bob Harras.
And the rest-as the saying goes-is history.
