The Rhinos backed up last weekend's triumph over the Catalans by running in six tries against the lacklustre Trinity, while full-back Ashton Golding also kicked all seven of his attempts at goal.
McDermott found himself under pressure a few weeks ago after seeing his side crushed 66-10 at Castleford but having been given a stay of execution by the board, has engineered a significant improvement.
The 47-year-old has now praised his side's performance in front of their fans at Headingley, although he admits they were given a slightly easy ride by their under-par opponents.
"It was a good, solid one. We're pleased to back up from last week's good performance," McDermott said.
"There were some good passages of play and I thought we were great defensively, but I don't think we saw the best of Wakefield."
