Respected coach Butch Harmon believes Rory McIlroy was wrong to chase the monstrous length being achieved by Bryson DeChambeau and has told him to stop over-analysing his game.

McIlroy, who next week goes in search of a long-awaited victory at the Masters which would complete his career Grand Slam, admits himself his game was affected trying to replicate the extra-power strategy the reigning US Open champion has employed over the last year.
