“I can’t say he’s my friend,” Cousy, a Worcester resident, said about Fauci on Monday from his winter home in Florida, “but I’ve been in his company three times and I’ve been telling people for 30 years that he’s my hero.” The 91-year-old Holy Cross and Celtics legend remembers first meeting Fauci many years ago at the Virginia Dental Association’s annual dinner. Ken Haggerty, co-captain of HC’s NCAA championship team in 1947, when Cousy was a freshman reserve, served as president of the association and invited Cousy to attend because Fauci was the guest speaker.
