CHICAGO (CBS) — Before the Blackhawks celebrate their Stanley Cup championship with fans on Friday, they’re thanking Bruins fans and the city of Boston for their generosity during the playoffs.

“Hockey is a tough game. As impressed as we were by the strength, talent, and competitive spirit of the Boston Bruins on the ice, we were deeply touched by what happened off the ice,” Blackhawks owner Rocky Wirtz and president John McDonough said in an ad the team took out in the Boston Globe. “Rarely have we experienced the hospitality you afforded us throughout the playoff series between two incredibly gifted teams.”

“Like the rest of the world, Chicagoans have been reminded in recent days of Boston’s strength. Please know we tip our hat to your city’s big heart and gracious spirit. You lead by example and have set the bar very high for others to follow,” they added.
