The reigning champions are just four points behind leaders Wigan with two games in hand after extending their unbeaten run to eight matches, a far cry from last year when they were outside the top six.
"It doesn't take much to be miles ahead of where we were last year," McDermott said. "We're reasonably happy with where we are but things can quickly turn and we're not going to get carried away. We're 12 games in so there is half a season to go before we start to think how it looks in terms of the play-offs."
Leeds never looked back after opening up a 12-0 lead inside six minutes thanks to tries from Kallum Watkins and Mitch Achurch. Prop Ryan Bailey marked his return from a four-match ban with his first try of the season, centre Carl Ablett touched down twice and captain Kevin Sinfield kicked seven goals from seven attempts on his 450th appearance for the club.
"We looked impressive for periods, in that first half especially, but we knew this game was going to be a fight at some stage and there were spells when they made a contest of it," McDermott said.
"In the second half you've got to give a lot of credit to Bradford, who threw a lot at us, but I thought we were very good. Things are working for us at the moment, they're making that extra effort."
McDermott dropped a hint that veteran prop Kylie Leuluai would be offered a new contract after revealing in the week that he wanted to postpone his retirement plans for a second time.
"Kylie is looking as fit and strong and rejuvenated as we've seen for a while," he said. "He wants another year and, however old he says he is, he's got another 18 months in him. He's looking really good."
Bradford trailed 30-6 at half-time but rallied in the second half, with prop Ben Evans marking his home debut with a try and winger Elliot Kear grabbing his second in the final minute. It meant a third consecutive defeat for the Bulls but coach Francis Cummins was pleased with his side's character.
"They were too good for us at the start," he said. "You can't allow Leeds to get four tries in front. We had a few players out but we showed a lack of composure. There was a real good reaction after half-time, though, and I'm happy with the character. They work hard for each other, they are trying really hard. We've hit the wall results wise but we will be better."
