Mango (Johnsson) is the only top 6 LW in the entire Leafs organization. The rest are depth or middle six players. Unless the Leafs are getting a significant, long term LW upgrade at some point (part of that trade or ACGM), they will not trade him.
If you want value, the Leafs are deep on the RW. Our depth looks like (In bracket is where they project skill wise, not nessisarily where they are now):
