i think the best thing about the team so far is the 2nd line. read-lecavalier-simmonds has been, by far, the most consistently effective unit on the team. and read-levcavalier-schenn have carried that production over to the PP.
on the downside, i think giroux has been severely underwhelming. he hasn't scored, but beyond that, he hasn't been strong on the puck, he hasn't active in the corners or in front of the net. i know he rushed back after the golf thing, and i give him credit for that, but his production has not matched his playing time. voracek hasn't scored either, but he's flashed a whole lot more than giroux has, even despite nearly 6 fewer minutes of icetime per game.
on the blueline, i think the flyers have held their own and maybe even played a step above that, but they still don't have a #1, and there's really no telling how long meszaros, grossmann and timonen are gonna be able to stay healthy.
in net, i'd say they're okay. they're certainly better off than last year, which isn't actually saying all that much.
on the whole, all 3 units look average at best. and with big extensions kicking in for giroux and read next year, offset only by the impending free agency of timonen, meszaros, schenn (RFA), mason and emery and with the flyers developmental system being perennially ranked in the bottom 10, i'd say any major, franchise-altering moves would best be made sooner, rather than later.
(but then, i'd have made any such moves last season, when it might have yielded seth jones, in addition to whatever prospects/draft picks you could have gotten in deadline/pre-deadline trades of matt read or kimmo timonen or wayne simmonds or talbot or coburn or schenn or briere. but that's just me.)
