The Capitals have a habit of celebrating accomplishments no one cares about (see the Southeast division championships).
So of course they celebrated their “2015 Winter Classic Championship” by hoisting a banner in their practice facility. This is probably a fan-made banner (we hope so based on the ridiculousness and the “awesome!!!”) but we wouldn’t put it past the Capitals.
