By Henry Jacobs After the opening four rounds of the 2015 National Rugby Championship Brisbane City sit in a commanding position, having won every match comprehensively to lead the competition at the halfway mark. Thursday’s 55-29 defeat of the North Harbour Rays at Ballymore was City’s eighth win in a row, across the 2014/15 seasons, and saw the side maintain their grip on the Horan-Little Shield. “We are very happy with our start, last year we didn’t manage to win four in a row until our run through to the title so to be four from four at this stage we are very happy with where we are,” Brisbane City coach Nick Stiles said. “Every game we have played we have played for 80 minutes, we might of had some periods through games where we have dropped off or gotten a little bit loose and tried to force the pass, but what has pleased me the most has been our dedication to playing the full 80 [minutes].” City have averaged 42 points a match this season, scoring 24 tries in
