Johns nominates Lockyer as NSW's
biggest worry

New South Wales has nominated brilliant fullback Darren Lockyer as the greatest threat to the Blues' hopes of wresting State of Origin supremacy back from Queensland this year.

The Maroons, who have carried interstate bragging rights since 2001, are full of match-winners, but Blues captain Andrew Johns says Lockyer is the biggest worry.

Lockyer has been Queensland's most influential player over the past two series and Johns says he must be watched.
