The "LCB Line" of Reggie Leach, Bobby Clarke and Bill Barber, which was the Flyers' top line on the Stanley Cup championship teams of 1974 and 1975, will join the 1990s-era "Legion of Doom" line of Mikael Renberg, Eric Lindros and John LeClair in its return to the Wells Fargo Center, which it helped open in 1996.
