Why has Rory McIlroy lost form?

Consnsus opinion is that it's the fault of his changing clubs in that massive deal with Nike. However  I wonder if he's been distracted recently...


His girlfriend, world tennis number 1, Caroline Wozniacki has been posing for promotional material for a new sports lingerie range. The Mail have some diverting stills.

Here are some others that I found that may illustrate why Rory is off his game.

 Maybe this has put Rory off of his stroke...
