In the offseason Briere should blow up the team a bit, because right now they are in no man's land where they aren't good enough to make the playoffs and not bad enough to get high draft picks. They still need to get high draft picks if they want to become cup contenders in the future.
I think they should trade Konecny rather than extentend him. He is 27 already and is in his prime years which won't be put to best use in Philly unfortunately. I'm guessing he would want an 8 year extension which would kick in when he is 28 would run until he is 36, which is just not ideal for Philly right now since they can't maximize the use of his prime years.
Right now Flyers really need to get themselves a guy that could in the future be the teams 1C and I don't see them getting that through trades right now. They could also use some better prospects elsewhere in the lineup, but getting a future 1C is by far their biggest need.
Lot of fans want this team to go out and trade for players so they could become contenders sooner, but I'm willing to stick it out with the longer route of drafting and developing players for couple more years and then trying to get into the playoffs when Michkov arrives.
Kulich seems like a pretty good fit for them since he is listed as a center/left wing in here which are positions Flyers could use some help in on their forward core. Savoie is another Player which they could be interested in since he is a center.
He's undersized, won't be an NHL center and doesn't play D.
