Everyone in the media keeps saying how the Leafs are basically locked into the 3rd spot in the Atlantic, but they're only 4 points ahead of Tampa with 2 head to head games left. They're also 8 points behind Boston and Florida with a game in hand against the Panthers (plus 2 head to head) and 2 against the Bruins. Suddenly getting cold or hot for the last dozen games could easily see them move up a spot or down to the wild card.
They're 11 ahead of Detroit and 10 ahead of Washington so it would take a pretty spectacular collapse to actually fall out of the playoffs, but I see no reason why WC1 should be considered off the table and Atlantic 2 (or even 1) is theoretically possible although pretty unlikely.
