The coach said: “Lewis Murphy was outstanding on the wing and he is going to get better and better. He has the raw pace that’s invaluable for a team.
“Kobe, Oli Farrar, Charlie Abraham and Robbie Butterworth - who started at full-back - got called up from reserve grade and did themselves proud.
“It is heartening for us as a coaching staff, but also the group that if needed sometime during the season we can go to those depths.”
Playing in front of a near-10,000 crowd will prove vital experience for the rookies, Poching added.
“They haven’t really done a pre-season with us,” he said. “I have been monitoring how they’ve trained with the academy group and they have all performed well and given their best. That’s why I had no issue giving them a crack [on Boxing Day].
“I was always of the mindset that whatever happened, they were going to emerge better for the experience, for being at a stadium like Headingley, against a quality side like Rhinos, in front of a packed crowd. They will take a lot from those experiences.”
