what in gods name is that flyers trade

Not one of those trades come even close to fair.
-Why would Philly take on a cap dump in Saad and a dman signed till he's like 40 in Keith. Thats not even mentioning that you are getting some of their best prospects in Frost, Myers and young, cheap solid players in Sanheim and Laughton. Zero incentive to make that trade.
-Why do the Oilers give JP, whos cheap and is only 20 for an overpaid 3rd line centre? Anisimov was only a 40 pt centerman, playing a full season with Kane. Not to mention the Oilers can't afford him.
- The Leafs best prospect in Sandin is worth more than a 3rd pairing, pp dman in Gustaffson. You clearly didn't even think of the value here.
-Im sure Ottawa is jumping at the chance to get Seabrook who while still a serviceable 3rd pairing dman, is getting paid like a top pairing guy and is already getting old. Then you throw in Crawford, who is also making lots of money, and has had a few years in a row now with some serious injuries. Thats what every team wants.

I hope you really didn't believe you could get rid of all you bad contracts, while gaining assets. Then you go ahead and sign the top 3 free agents. You'd be lucky if 1 or 2 of the signings/trades actually happen
