I haven't seen anyone mention this but every team should have 4 games played if I'm not mistaken. Most do, however...NYR, Bos, Nash, Calgary all have just 3 games.
Pitt, Col have 5 games. Probably just a scheduling oversight but this can be corrected by matching up the schedule for week 1 for those team's affected.
Solution 1 matchup NYR v. BOS & Nash v.Calgary
Solution 1a Delete Pit v. Col matchup.
This should balance out week one.
