Not really.
Johns made a name for himself with Flash and JSA, upped his profile with Teen Titans and exploded with Green Lantern.
Then he went a loooooooooooong period as a company man, salvaging whatever the company told him to, sometimes writing 3 or 4 monthlies at once - and his writing suffered for it. He is now at a weird position, where he's at the same time above and bellow Didio, but before that he almost ascended to the editorial ranks at least twice (first was when DC was planning sort of an Archictets initiative, along with Waid, Morrison and, I think, Rucka (but maybe it was Winnick) back in the days of Inifnite Crisis, and the second one was during the Brightest Day era).
Johns has executed a lot of mandates, make no mistake.
