The reigning Super League champions scored 10 tries, all from the backs, with Hall leading the way. Leeds’s win was their first in four games. Winger Ben Jones-Bishop and centre Zak Hardaker scored a brace of tries each, while Brent Webb and Carl Ablett also joined in the romp.
“Wingers need opportunities to score and Ryan hasn’t had many in recent weeks,” said Lowes. “When he gets chances he knows how to take them.
“It was very pleasing that all our 10 tries came from the backs. We had some very strong performances out there.
“We had to defend strongly early on and it gave us the platform to cut loose.”
Rob Burrow returned from a two-match injury absence and took another blow to his troublesome shoulder, but Lowes said: “Hopefully it is not too serious.”
A series of penalties and handling mistakes left Leeds needing some desperate defensive work as they were pinned back on their own line in the opening 10 minutes.
Leeds opened the scoring in the 25th minute from their first threatening attack. Slick passing by Kevin Sinfield, Lee Smith and Brett Delaney on the right ended with Ablett cutting inside to touch down, Sinfield failing to convert.
Sinfield and Smith then combined and Ablett turned provider to send Jones-Bishop squeezing in at the corner, Sinfield goaling. Leeds had their tails up and after Sinfield was grounded, the ball was ferried out left for Hall to score his first.
Jones-Bishop collected his second try just before half-time after a glorious break by Ablett was carried on by Smith to leave the Rhinos leading 18-0.
The Broncos hit back with two tries at the start of the second half, with substitute Luke Dorn’s long pass exposing poor Leeds marking as winger Kieran Dixon crossed. Then Dorn cleverly dummied his way through and Witt added the goal to leave eight points between the teams.
Leeds’ nerves were steadied when Hall held on to Sinfield’s angled kick to score his second try and then repeated the act to chalk up his hat-trick, Sinfield improving both tries.
Hall raced in at the corner for his fourth try and 11th of the season. Full-back Brent Webb scored the Rhinos’ eighth, and two late tries by Zak Hardaker completed the romp.
