Angotti, a native of Toronto, earned an engineering degree at Michigan Tech University, where Tony Esposito would later graduate. He signed and made his NHL debut in 1964 with the Rangers, then was acquired in 1965 by the Blackhawks, for whom he played two seasons.
In 1967, Angotti became the first-ever captain of the expansion Philadelphia Flyers, registering a career-high 49 points on 12 goals and 37 assists. He joined the Pittsburgh Penguins in 1968, then returned to the Blackhawks for four full seasons before finishing his NHL career with the St. Louis Blues. There, he later served as coach. For the 1983-84 season, Angotti was coach of the Penguins.
Angotti always considered Chicago to be home. Indeed, the closing entry on his playing summary is a brief tour with the Chicago Cougars of the World Hockey Association in 1974-75. Thereafter, Angotti was a welcome voice for a spell on Blackhawk broadcasts -- TV, radio, pre- and postgame. He had a keen eye and a forthright style, often spiced with a sense of humor. Angotti loved hockey, almost as dearly as he loved to laugh. Eschewing a wallet, he carried a wad of cash rolled up his sock.
Regardless of the assignment, Angotti always brought energy with him. Fans gravitated to that. Decades after he played here, Angotti was featured one evening at the Blackhawk Alumni autograph signing booth. Venerable supporters of the franchise formed long lines along the 100 Level of the United Center. When Angotti arrived, flanked by security, he heard a familiar chant.
"LOO!! LOO!! LOO!!"
