St Helens coach Nathan Brown picked out stand-in full-back Jonny Lomax for praise after his hat-trick in the 36-10 victory at Bradford.
Lomax, who made his Saints debut as a full-back in 2009, was switched from his customary scrum-half role to plug the gap caused by injury to skipper Paul Wellens.
And he was the star of the show, running in three tries in an impressive win, whilst England back-rower Jon Wilkin also shone after being moved into the halves to form a new partnership with Gary Wheeler.
"Jonny certainly played well," said Brown of 22-year-old Lomax. "The best modern-day full-backs are half-backs. He's athletic, he can pass and kick and see the game well. I don't think it was a genius move.
"Jon (Wilkin) has played in the halves a lot of times for St Helens over the years. He's a very controlled player and he helps us play with a bit of composure.
"We're improving. From round one to four, we have definitely got better.
"I thought in the first 40 minutes we played with good discipline and control. We let ourselves down in the second half but we did things more consistently for longer today.
"I'm sure we'll improve again. It will be a big challenge next Friday. Leeds are a good side and they did the competition a good service last night with the way they performed."
Bradford never fully recovered from their woeful start but salvaged some respect with second-half tries through Brett Kearney and Elliot Kear.
"We had very little possession in the first half an hour," said Bulls coach Francis Cummins. "They got a good roll-on and we spent too much time near our own goal-line.
"You can't afford to play against the main teams without the ball. At the back end of the first half we asked some questions. We opened them up but couldn't finish off.
"I was pleased with the fightback and in the second half we were able to trade sets but we need more quality than that to beat St Helens."
