My post, and your post, have absolutely nothing relating to each other.
Okay. Then please elaborate how you, based on a three game sample size, know Sedlak better than Tortorella does.
Of course Sedlak isn't going to have a Kunitz-esque career. But what's the risk for the Flyers, again? Not only are they (almost certainly) gonna miss the playoffs this year. They also have Sean Couturier, Cam Atkinson, Patrick Brown and Owen Tippett injured.
They currently have three rookies/kids playing center. What's the harm in picking up a 29 year old with a little bit of experience, who's been productive in the KHL, and at worst should be a useful AHL player for them once their team is healthy?
The Flyers are in no position to be trading assets for established players. That'd be a lot more stupid than picking up some tweener on waivers, who will not make their team any worse than it already is.
