The 2015-16 NHL season officially gets underway on Wednesday, and those involved will have a few new rules and regulations to get accustomed to.
3-vs-3 Overtime
The most obvious difference from this year to last is that the five-minute overtime period will be played with three skaters rather than the four that teams have been allowed in recent years.
A team's strength will never fall below three on-ice skaters, so in the event of a team carrying a power play over from regulation time, or being awarded a man-advantage chance, they will add one (or two for a five-on-three) player(s) to their attacking unit.
