.409 - The win percentage for the home team in outdoor games since they became an annual (and now semi-annual) tradition back in 2008. Going back to the inaugural Winter Classic a decade ago, the away team has won 14 outdoor games compared to just nine by the host team, the visitors holding a slim goal margin of 62-59 over that span.
The trend was heavily weighted towards the visiting team early on, with away teams taking eight of the first ten outdoor games; since then, it’s balanced out a bit, with home teams winning four of the last five.
