Mainly because they were awful defensively and after the first couple months stopped producing too. Seems like it will be Z-McT-Terry to start camp.
It seems odd to split McTavish and Vatrano after his season last year. I'm too Getzlaf to look it up but I remember seeing Vatrano's stats without McTavish and it wasn't pretty. Vatrano-McTavish-Terry seems to make the most sense to me. Zegras should be the third line center.
