Last week, the Ottawa Senators made the somewhat controversial decision to put Matt Murray on waivers. Though I’m sure the team would have loved if another organization had decided to take a shot on Murray, there was never much chance of that happening. Practically, putting Murray on waivers meant that the Sens were sending him to the AHL to play in Belleville. Whether Ottawa management, particularly Pierre Dorion, handled the whole situation appropriately or not is one question. Today, though, I’m interested in a different one: How does Murray get back to Ottawa? Presumably he was sent down to work on his game; what are the criteria for his return?
