Was there any rule changes to NHL?

[MaddyMax]

Each time i checked the score so far during the pre-season, its higher than average....

was there any new rule changes coming into this season?

Failed challenge results in 2 minute penalty

Faceoff violation resulting into 2 min penalty. Though they have toned it down already and I doubt we will see this rule in the regular season.

gtfo... and the faceoff bs... makes it a more intense game, but they're already great!
Vegas needs more overs?

It's just preseason. ...it will be back to normal in a few months.
