As note of clarity:

I do believe Yamamoto is tradable but, with EDM's lack of RW depth, I would sooner know for a fact the Brown is capable of playing top 6 (following his injury) and that Lavoie is ready for NHL action.

Additionally, Broberg should be given the opportunity to prove himself in the bottom pair, not as the optional #7. That does not help him or the team assess what they have in the player.
