Rovers maintained their 100 per cent record with a 45-18 win at Whitehaven last week, but Powell believes there is plenty more to come from his squad, who are listed as favourites on the rugby betting sites.
Powell said: “We’re winning games, but at the moment we’re not playing as well as we can.
“There is some work to be done, but you’d expect that when we’re only five games into the season. We’re looking forward to improving.”
March said: “We’re going to go to Featherstone as massive underdogs, but it’s the first time people will see us on Premier Sports this year and we want to put in a good account of ourselves.”
