The French Connection center established many franchise records that remain unchallenged decades later. It'll probably stay that way.
Who is the greatest Buffalo Sabres player in franchise history, Gilbert Perreault or Dominik Hasek? They are both enshrined in the Hockey Hall of Fame and were among the NHL's best players of their respective eras, but it's the French Connection center's longevity that earns him the GOAT label.
Perreault is known as "The Original Sabre" because the newly born organization selected him with the first overall pick in the 1970 NHL Draft.
