Slater impressed with Maroons' middle forward depth
Coach Billy Slater is thrilled with the depth in Queensland's middle forward positions, with a quartet of rising guns catching his eye ahead of the State of Origin series.
Parramatta lock J'maine Hopgood and Canberra No.13 Corey Horsburgh are yet to play Origin but have impressed.
Tom Gilbert, one of the Dolphins' best at lock this season, shone in Game Three of last year's series in his Origin debut.
