Fedorov, Kozlov, Konstantinov and Fetisov opened the 1995 season with the Wings, and the group was ultimately completed a couple of weeks into the campaign when Larionov was acquired from the San Jose Sharks in exchange for forward Ray Sheppard.
Together, they were a menacing group that dominated the puck and helped lead Detroit to a 62-13-7 mark during the 1995-96 season, and eventually a Stanley Cup the following year. It was not only one of the best lines in hockey, but also, arguably, the most entertaining. Unfortunately, the Stanley Cup was the last time the group played together as Konstantinov had his career ended shortly after the Finals due to injuries suffered in a limousine accident.
Here's a four-minute television segment that talked about group a decade-and-a-half ago. When the NHL was still on Fox (glow pucks!) with James Brown. Ah, memories.
