So I'm playing Be a GM mode and I have no idea how I was able to pull off all these trades, but heres, the lineup of the Leafs so far this season. It's still a work in progress, but it's very close to being a juggernaught for a long time.
Van Riemsdyk - Datsyuk - Kessel
Sven Baertschi - P. Kane - Sven Andrighetto (85 rating)
Nazem Kadri - Vincent Lecavalier - Matt Frattin
Marcus Messier - Nathan MacKinnon - Alex Galchenyuk
Morgan Rielly - Jake Gardiner
Henrik Tallinder - Jesse Blacker
Stuart Percy - Olli Maata
Reimer
Ellis
I also somehow drafted a bunch of good players, and amassed first round picks like a crazy person Example: I drafted Mackinnon, Barkov, Domi, Andrighetto in Rd 1 of 2013 with the picks I amassed. If I remember any other prospects I drafted/acquired I'll post again.
