HULL KR caretaker boss Chris Chester offered no excuses for his side after Widnes ran in four second-half tries to win 28-10 at the Select Security Stadium.
Chester felt the Robins were competitive at 10-4 down at half-time, but their game plan unravelled thereafter.
“That was pretty difficult. I thought we competed for the first 40 minutes but again the second-half has let us down,” he said. “I thought we had the right personnel in the second-half to get the job done but I was wrong, so obviously not.”
Kris Keating’s touchdown after 23 minutes cancelled out Jack Owens’ earlier effort, before Chris Dean’s try and Danny Tickle’s goal gave the hosts the lead at the interval.
After the break Joe Mellor, Kevin Brown, Stefan Marsh and Rhys Hanbury all crossed as the hosts took control, with Travis Burns’ converted try the only response the Robins could muster.
“Again I have to go back to the drawing board and see where we are going wrong. We got what we deserved and if you come up with that many errors then you don’t deserve to win,” Chester added.
Chester felt Jason Chan was one of few players who came out of the defeat with any credit and warned that things need to improve quickly.
“I thought Jason Chan had his best ever game for the club – the people around him let him down,” he said. “If we keep playing the same way then we will keep getting the same results.”
Widnes coach Denis Betts, meanwhile, was pleased with the way his side remained cool and built a winning scoreline after half time.
“We talked about half-time about keeping our composure and we managed to do that,” he said. “We know where we could find the space we needed to get the points that we needed.
“I’m pleased that we have kept hold of our play-off place. It keeps our confidence high going into next week.”
