The Broncos lost their Championship Shield encounter at Dewsbury 25-16 on Monday, but Henderson saw some signs for optimism.
“I was proud of our middle boys today as I’ve been putting them under a lot of pressure, I felt they’ve been poor,” Henderson told his club’s official website.
“Dewsbury are a big, tough and physical unit and I think we contained them.
“James for me has some leadership quality and he probably doesn’t realise that yet.
“I do believe he’s got something in there and I’m sure we’ll unearth that in the coming seasons.
“It was a great opportunity for him to lead the team, I thought he done well and let from the front.”
