The 36-22 win at Hull was job done for Leeds Rhinos.
Rhinos will go into next week’s Ladbrokes Challenge Cup final against Hull KR on a run of six successive victories and now with a four point lead at the top of the First Utility Super-8s table.
McDermott left out four players from last week’s team ahead of the final and Leeds came through the game with no major new injuries.
“There’s no big ones, which is great,” McDermott said of the injury situation.”
He added: “I have never said the final is a distraction, it’s good. We’ve been looking forward to Wembley for a few weeks.
“We’ve been wanting to play well because we’ve got Wembley coming up. It is a great place to be – and even better to win there.
“We have got no apathy towards it because we won last year, we want to go for it again.”
McDermott said he has a “good steer” on his line up for the final, but will review it over the weekend and has yet to make a final decision.
Of last night’s win, he said: ““It was certainly a tough one, we had to tough it out.
“Hull had a huge go, as did we. Had we lost, I would not have been moaning about anything.
“I thought it was a very good game. It was a real test of mental toughness.”
Youngsters Ash Handley and Ashton Golding both made errors under the high ball, but McDermott said they will benefit from the experience in the long-run.
Rob Burrow, who started at scrum-half, scored a brace of tries in the second half, taking his career tally to 200.
McDermott said: “He has been the quiet assassin, he’s been very effective for us.
“I don’t need to tell people how good he is, but he had a big influence on that game.”
