I went with what I thought they would do. Leaving Voracek exposed depends primarily on what's available in FA or trade. Frustrating as he is as a player, Jake's a top-6 right wing in the league. Letting him go leaves a huge hole that I don't risk without a plan for filling it.
Laughton's a nice player, but he's a 4th liner on a good team (who can move up, true), which, as it happens, the Flyers are. He's also a pending UFA, so if you want to keep him, you just talk contract with him right up until the expansion draft so he knows where he stands with you, and can re-sign if selected.
I doubt they put Patrick out there. He's started slow, but you can definitely see the skill. And he doesn't seem to have a work ethic issue like most high-pick busts seem to have. He's going to be a good player, I think, and giving up several years of low-cost Patrick would seem a bad idea given the stagnant cap situation over the next few years. Plus, even if the Flyers sour on him, as long as he comes out of this with his headaches under control, there's bound to be a team willing to take a chance that he's just a slow developer that you can make a hockey trade with.
