It looks like you have the right ideas here, but the values of players and picks are different than how I perceive them. Giving up a 1st and 3rd to rid Marleau's contract is a hefty price for one year of a contract. Since the Leafs rejected a Nylander for Pietrangelo, I can't see them doing a similar one-for-one for Barrie, Columbus' trade is interesting... it's a bit of a lateral move between Boone and Kadri, but something worth thinking about. Thanks for taking the time to put this together... it's always hard and always a lot of criticisms from people!
