Editorial: New RKCR/Y&R chief arrives at a good time

So Rainey Kelly Campbell Roalfe/Y&R has decided to shun the open market for chief executives. Instead, it is promoting from within. Congratulations to Richard Exon, who joined as the managing director less than two months ago. His ascent has been rapid, but he inherits an agency in rude health. He needs to tap the existing momentum, and convince the remaining staff there's life after James Murphy.
