What happened: Toronto fell 4-3 in a shootout to Vegas on Thursday with McKenna recording an assist. His top burst tracked at 23.34 mph via NHL Edge, which began logging speeds in 2021-22. The mark sits in the 99th percentile league-wide this season.

Why it matters: The speed adds a second dimension to a rookie profile built on playmaking through the WHL and NCAA. It puts the same McKenna who set the 18-year-old speed mark in direct comparison with recent teenage peers. Toronto is testing how that straightaway gear fits its rush structure early in 2026-27.

What to watch: Watch whether McKenna holds a top-six rush role and whether his burst leads the team again next game.
