Though O'Ree, who scored 14 points (four goals, 10 assists) in 45 games during two NHL seasons, enjoyed the unqualified support of his Bruins teammates and of many fans who were dazzled by his speed, he also heard taunts -- and worse -- from the crowd.
"In the penalty box, stuff would be thrown," he said years later. "They'd spit on me."
In one game against the Chicago Black Hawks (as they were then known), an opponent directed a racial slur at O'Ree and butt-ended him in the mouth, knocking out two teeth and touching off a melee.
"It would have been incredibly difficult for Willie," Subban said. "Racism in sports even today is still talked about so much. It comes in so many different forms that it's sometimes hard to tell when it's happening. It's not just name-calling and things being said. What Willie did in breaking that barrier and coming through to change the sport; in my opinion, he should be in the Hall of Fame.
"A Hall of Famer isn't just the guy who put up great numbers. It's the guy who has changed the sport for the better, who has had an impact. Willie definitely had an impact on hockey and he deserves to be recognized as a Hall of Famer, just as much as a guy like Wayne Gretzky. His impact on the sport is just that great when you think about it. I wouldn't be playing in the League if it wasn't for Willie O'Ree and a man like Herbert Carnegie (a brilliant 1940s and 1950s playmaker in the Quebec Provincial League and Quebec Senior Hockey League)."
Subban said O'Ree's positive example is one that he, and other players, can and should follow and share.
"There are so many guys who can be role models in this way," he said. "We have so many guys in the NHL who can lead by example and I embrace being a role model for a lot of kids.
"The special thing is that I'm able to do a lot of this while I'm playing. You have to remember that when you're in the NHL, you have the platform, and you'll never have a bigger platform than when you're playing."
On the 60th anniversary of O'Ree's historic achievement, Subban will pause to think of his friend, a hockey legend because of who he was, and is.
"Willie had an ability to turn the other cheek to racism and say that he wanted to help the League, to be a big part of its history," Subban said. "Because of Willie, the NHL is more diverse today than it's ever been with players coming in from all over. We know we have an opportunity, and we're thankful for it, because of him."
