The Bulls ran in six tries on a heavy pitch and led 24-6 at the break but allowed Salford to twice claw their way back to within six points of their hosts before putting the game to bed with a late try and a penalty. Cummins was quick to praise Salford for the way they fought back in the second half but also questioned his team's approach.
He said: "We defended really well against them but you can't come out of a bog after defending three sets and try to come up with big plays - you have to play a bit more conservatively, think about field position and get yourselves back in the game. You have to earn the right to play and we were perhaps a little bit naive during that spell."
He added: "We went a long time without the ball but that was all credit to Salford who picked themselves up well at half-time.
"Eventually we went back to what we were doing in the first half and turned them around, trading set for set, and when we did that we looked really good."
Cummins admitted that when Salford clawed an 18-point deficit back to 24-18, reality kicked in.
"When we got to that situation the lights came on and we got our kicking game going again and began to trade set for set," he said. "If we find ourselves in that position again, next time I hope we can handle it a little bit better.
"They have worked really hard and I can't be disappointed."
Salford's interim coach Alan Hunte said: "They handled the game smarter than we did in the first half - their kicking game through (Jarrod) Sammut and (Danny) Addy was outstanding whereas we had a couple of kicks that went close but dead and that relieved the pressure valve.
"Sammut and Addy were probably their most dangerous weapon. But I've got to commend my guys for their effort, especially in the second half. In reality I think it was a bit closer than the final score suggests."
