That might be a feel good position applied towards hope, but its not valid.
Past completed games can't impact future results .. Leafs could have won 10 straight games and nothing would prevent them from losing 10 straight games thereafter because those results are exclusive of each other.
Case in point the Tampa Bay Lightening finished last season with 128 points on the season and then got swept in 4 games in the playoffs to Columbus. Based on past success using an 82 game sample size you should have awarded TB the Cup and not expected a 4 game small sample size but recent events to become a 4 game sweep. During the regular season TB beat Columbus 8-2, 4-0 and 5-1 outscoring them 17-3 .. The #1 overall ranked team getting swept by the WC#2 team that finished 30 points behind them was not projectable using past performance.
Our Leafs have no doubt been hit with a lot of injuries this year but that isn't really a valid excuse either because they're are teams like Pittsburgh who are among the most man games lost and still among the hottest teams in the league, playing without players like Crosby and Malkin during stretches etc.
Columbus let goalie Bob (signed for $10 mil) and team leading scorers Panarin (signed for $11.6 mil) and Duchene (7 year $8 mil contract) walk out the door via free agency and also hit hard by injuries this year and are still 8th overall in the current standings and ahead of our Leafs ... What would be the equivalent Leaf impact say Andersen, Marner and Nylander all leaving with no return, to try and equal the impact that same level of players missing this year?
So what happened to the Leafs in December really doesn't matter anymore today as I mentioned those games are already reflective of getting back into the playoff race and Leafs 68 current points reflect that accurately. You just can't hang your hat of past achievements to accurately predict future events when it comes to sports. Its always about the here and now and what happens going forward.
