If the Leafs lost to the Sens, it will be HF mayhem.
In any event, Leafs-Sens brings me back to the early 00s when they had some wars that the Leafs always seemed to win despite having the inferior team, on paper. Those were some fun series.
Put me down for team chaos, although it's not necessarily that the Ottawa Senators winning would cause that (though it would be a factor), it would be more about Toronto getting eliminated early again.
