The Blackhawks magic number to clinch the division is 2points. So either 1 more win for them or 1 more loss for the Blues.
To clinch division is 9 points.
To clinch presidents trophy is 13points.
Edmonton has to play Anaheim back to back before playing the Blackhawks so it looks like the Blackhawks will be playing against 3 teams who wont have a shot (Preds, Oilers, Flames)
Penguins have Montreal and Boston one right after the other. However, they play 4 games with the bottom 3 teams.
So in conclusion, Guin's should win those 4 games but have a tough 5 games.
