Having begun last season in a familiar role as a key forward, Liam Jones has declared he will head into the 2018 campaign "clearer" in mind after his career was reshaped.

Jones emerged as one of the league's success stories in 2017, his career appearing all but over before he was sent to full-back, becoming a key piece of the rebuilding Blues. So impressive was Jones in the last line of defence that he was awarded a two-year contract extension.

The Blues have detailed plans this season to be a more attacking side, having averaged a league-low 72.5 points last year, but curbing opponents will still be crucial if they are to improve on last season's six wins, one less than 2016.

"I feel really good. I probably feel a bit more clearer than this time last year. This time last year I did the whole pre-season as a forward-line player," Jones, who turns 27 this month, said.
