Stolarz & Leier are good bets plus Goulbourne depending on whether he receives a contract this offseason or not, the Flyers still have the option to send him back for his overage season in the WHL as well.
Laughton & Gostisbehere are possibilities for either NHL or AHL at this point. Hagg is iffy as well since it's unknown at the moment if he'll stay here or go back to Sweden.
Akeson, McGinn, and Laughton will be competing for NHL forward time.
Gostisbehere, Morin, and Hagg will be competing for NHL blueline time.
Stolarz, Leier, and Goulbourne should be joining the AHL roster as well as the losers of the above battles with the exception of Morin...who will be back to juniors if not NHL.
Right now, I think the only winners we will have are Akeson and Laughton as long as they haven't given up on Akeson from that one mistake.
I think Laughton earns 4th line center if Lecavalier or BSchenn are traded, 4th line winger if they both stay.
