Murray was trying to sell Alfie on accepting the Senators contract offer with the main selling point being if the Senators pay Alfredsson his ask the team would not have the available salary to add players, specifically Bobby Ryan.
If Alfredsson signed a team friendly 1 year deal, we would have probably still traded for Ryan, and I assume not signed MacArthur.
Another scenario was David Clarkson signing in Ottawa, but I think Ryan was the player specifically brought up by Murray in the Alfie negotiations. In which case, we probably would not have traded for Ryan. Either way, we were looking to make a major add in the 5M-6M range, and I don't think Ryan was a response by the organization to Alfredsson walking, rather they were waiting to pull the trade on the deal until they could resolve the Alfredsson situation and in turn find out if they had enough to add Ryan.
