Yes, unfortunately I was born in 1988 so I couldn't experience the previous Flyer's teams. However, I was a fan already at about the age of 7 or 8 so I do remember quite a few players. Here are my picks.
1990s -
C - Eric Lindros
RW - Mark Recchi
LW - John LeClair
D - Luke Richardson
D - Eric Desjardins
G - Ron Hextall *I don't think any of our other goalies deserve this other than Hexy, a true competitor and our winningest playoff goalie, if I could, I'd put him on the 21st decade one as well, unfortunately he was waived in 1999 and retired the same year*
Coach - Terry Murray *1997 Finals, enough said*
2000s -
C - Keith Primeau
RW - Rick Tocchet *second go-around with us, including that playoff loss against NJ

*
LW - Simon Gagne
D - Joni Pitkanen
D - Eric Desjardins *I agree Blind, this guy deserves to be on both lineups*
G - Robert Esche *for a lack of anyone else I'm afraid*
Coach - Ken Hitchcock
