maybe only a little tweak to OT rules would help:

Damien Echevarietta of NHL Hockey Ops/Player Safety will be making his annual push for all OT to be always played with the "long change."

There's more NHL goal-scoring in 2nd periods (long change) than 1st or 3rd. He believes making that one change may settle more games in OT.
Bob McKenzie @TSNBobMcKenzie
USHL had 23% of its games go to OT (roughly same as NHL). USHL went to long-change OT, settled 10 per cent more games with that one change.
You just let teams switch sides before OT ... could very well affect how things go.
