Gaudreau received a warm response from the fans and scored two goals, but BU won 8-6. Eichel scored twice for BU.
"Everyone knows who Jack is and wants his time," Mullane said, "but for him to give up a night to come here for us has been great."
Boston Bruins defenseman Charlie McAvoy participated in the game for the first time as an NHL player. He played six games in the Stanley Cup Playoffs after leaving BU following his sophomore season.
"It's really special. It's obvious it's such a great cause," McAvoy said. "It's unbelievable to come back. It's a small thing you do to dedicate one night to coming out and playing the game you love. The proceeds and the support that you get from everybody it makes it pretty special."
More than $170,000 has been raised in the past three years, so the Comm Ave Charity Classic figures to continue to be a date to circle on the calendar for alumni for years to come.
"I think the money says a lot, but we're more impressed with the hockey community and how receptive the players have been and how receptive the fans have been," said Mullane, who co-organizes the event with Andrew Orpik and Justin Murphy. "To give up a Friday night in the middle of summer when you could be on [Cape Cod] or at a Red Sox game but you're here in a hockey rink, it says a lot about the Boston community and the hockey community."
