Northern Ireland's McIlroy was asked by reporters in the US about his reaction to the appointment of Love.
"It came as a big shock when they announced that Davis was going to be the next U.S. captain," McIlroy told reporters.
"It will be great to see Davis and (European captain) Darren (Clarke) go head-to-head at Hazeltine and they will be formidable opponents.
"But then also I'm surprised, and I feel they're overdoing it with the setting up of a task force and also talking about all the changes they want to bring in.
"It's been said by a few players since we won at Gleneagles that it's not rocket science why Europe have won the last three Ryder Cups and eight of the past 10, "he added.
Love has captained the US team before, at the 2012 Ryder Cup in Medinah, when they blew a 10-6 lead to lose the trophy.
"Davis is going to be a great captain and it was a freak we won at Medinah in 2012 and it was not supposed to happen given they had a 10–6 lead and if the States had of won Davis would have been looked upon as a great captain," McIlroy said.
"So I get the sense the States, what with their task force and everything that came out in Tuesday's announcement, that they're desperate to win back the Ryder Cup.
"And I will say it again because it's not that complicated why Europe has been winning," he added.
