What happened: Edmonton erased a 5-4 deficit in the final 10:40 of regulation to force overtime against Vancouver. Evan Bouchard scored three goals for Edmonton.

Why it matters: The comeback secured at least one point on opening night with a second point available in overtime. Bouchard became the first defenseman with a hat trick in a season opener since Mark Howe in 1980.

What to watch: Overtime will decide the winner and the opening-night record for both clubs.
