I'd add Marner in there in between the 2.
But at this point we don't know what this weekend was. A blip, a wake up call, the start of an early season tail spin. We won't know for a few weeks. Making a decision now is flat out asinine. But if it is a tailspin, you pull the trigger. Dubas has had 3 strikes on opportunities to move Marner and change the direction of this team. Doesn't get a 4th. New GM comes in, makes those decisions. Personally I think you have to move Rielly as a rental and both of Matthews and Marner. Less sure of Rielly, but if you're keeping him the other two have to go. Hard culture reset in the room. Move forward with JT/Nylander/Muzz/Brodie + the trade returns, UFA dollars, and a strong pool.
