The assistants on the coaching staff would go. I'd like to see one assistant with head coaching experience in the NHL brought on board, one coach who has had success in major junior and one coach who has had success as an assistant with other franchises.
Hope that one of Read, Raffl or Weise gets picked up in the expansion draft (preferably Read, but more than likely Raffl).
Lock up Jordan Weal to a 2 year prove it contract as well. 2 years/$2.5 million. 1.1 the first season, 1.4 the second.
Buy out Andrew McDonald or eat some salary in a move. He's got three years left, so eat 45% of the contract. Even if it means future considerations, a spot has opened up on the defense.
Promote Hagg, Morin, and Sanheim to the defense. Is it too much youth? Maybe. But get an experienced assistant who can handle young defenders and it shouldn't be something that blows up.
Obviously getting Oskar Lindblom under contract is a must, but so too is Mikhail Vorobyov.
At the draft, the hope is that one of Glass, Petterrsson or Negas is available when the Flyers pick. If they aren't, move down in the draft, grab a guy like Nick Suzuki and add more picks.
Finally, in free agency, there are only a few players I'd like to see them target. I'd like to see Jonathan Bernier signed to a 1 year/$3 million deal. A prove it deal and see how he responds with Dillabough as the goaltending coach (there's history there as well with Hextall, Dillabough and Bernier). Second, get Gostisbehere signed to a bridge contract. A two year deal for $4.7 million - 2.2 million the first year, 2.5 for the second. Finally, a legitimate veteran defenseman to help Gudas with mentoring the young guys. I'd love a guy like Karl Alzner or Shattenkirk, but that's too much money and years. A guy like Trevor Daley wouldn't be a bad target to bring on board to help with the younger defenseman.
Finally, last move. I know it's not a popular one, but at some point, Wayne Simmonds is either going to be extended or traded. As it stands, with Simmonds, Schenn and Voracek, there's nearly $18 million tied up on the right wing. That's too much money for one position. Three things: either move Voracek, move Schenn or move Simmonds. If you look at the three, who would bring the most in return? I think if it became known that Simmonds was available, you could start a bidding war and really land a treasure chest for him. At a minimum, it starts with a blue chip prospect (defense or forward), a young roster player (right wing preferably) and finally multiple draft picks (there needs to be at least a 1st in the package). I'm sure teams like Montreal, Boston, San Jose, Anaheim, etc...would all be interested.
