Salford head coach Ian Watson admitted the Red Devils were their own worst enemies on an opening night to forget.
“We gave Hull too much ball and made silly errors,” he said.
“Defensively, they were just running over us and it became a snowball effect. They were just playing too quick for us and we weren’t adapting to that. They played really well, Hull.
“We’re confident in the ability we’ve got in there but we need to work hard on doing the little things really well for each other and working hard as a team.
“We need to come out against St Helens (on Thursday) with the right mentality defensively. If you don’t defend, you’re not going to win anything.”
