What they say: McIlroy's peers have their say on Rory's masterclass
"I hadn't seen him since the Masters. I just said, 'I'm sure that you learned from your mistakes and what happened. Don't worry about that. We all make mistakes. All good players have to make mistakes before they can have successes'."
-- Jack Nicklaus
"If you are going to talk about someone challenging Jack's record, there's your man. Winning Majors at 22 with his talent, he would have 20 more years, so probably 100 more majors where he could be competitive. It would give him a great chance."
-- Padraig Harrington
"He's phenomenal, with the way he bounced back from Augusta, and with his maturity level for a 22-year-old. For any kids sitting watching at home right now, he's playing golf the way it should be played."
-- Graeme McDowell
"He can really change history again. He has got that kind of talent. When he breaks through, he can just open the floodgates. If he keeps learning and keeps going and keeps his head up, I think he's going to win a lot of Majors."
-- Ernie Els
"I think he's about 27 in golf years. He's very polished on experience. When I was 22, I didn't have the wealth of experience he has. I don't think we have seen a rookie come out with his composure and be ready to play on our tour right away like he is."
-- Davis Love III, US Ryder Cup captain for 2012
"When he plays well, he's capable of shooting low scores. If they make the golf courses longer, it will be 8,000 yards next year. We have Rory to thank for that."
"It certainly is a great story. You feel for a guy having what happened to him at the Masters, and you'd like to see a guy like that bounce back. What he did here at the US Open is dominate -- impressive work."
-- Matt Kuchar
"Everybody would agree he has probably got more talent in his pinky than I have in my whole body. He is unbelievably talented."
-- Brandt Snedeker, who beat Luke Donald to win 2011 Heritage Classic
"He has put on a clinic in how to play golf."
-- Butch Harmon, former coach to Tiger Woods
"He has lapped the field."
--Former World number two Colin Montgomerie
