The job doesn't get any easier for Queensland Maroons centre Justin O'Neill this year as the NSW Blues trade speed machine centre Michael Jennings for a big match player in Jarryd Hayne. 

The North Queensland Cowboy admits that he and the Maroons will have to prepare extremely well as both teams aim for victory in the all-important opening match of this year's Holden State of Origin series.

O'Neill spoke to the media earlier today.
