Jean and Denis Potvin
New York Islanders, 1973-77, 1979-81
Hall of Fame blueliner Denis was the first overall pick in the 1973 draft and is arguably the second greatest defenseman of all time (behind Bobby Orr). His older brother Jean may not have been comparable in talent, and while the defenseman did play for five different teams over 10 years in the NHL, his biggest seasons came playing alongside Denis in New York. Denis and Jean finished the 1975-76 season first and third, respectively, in scoring for the Islanders, with Hall of Fame center Bryan Trottier finishing second. Together, they won the Stanley Cup in 1980. In 1981, Jean played only 18 games for the Islanders, but his name was still engraved on the Cup, even though he did not qualify.
