Fifty years after the Pittsburgh Penguins officially join the NHL as part of the "Second Six," they are poised to become the first team from the 1967 expansion to win the Stanley Cup five times. A victory in Game 6 of the Final against the Nashville Predators on Sunday (8 p.m. ET; NBC, CBC, SN, TVA Sports) also would make the Penguins the first team since the Detroit Red Wings in 1997 and 1998 to win back-to-back championships.
