The defending Stanley Cup champs (finally), The Washington Capitals!
With the exception of two years at a boarding school, the first 27 years of my life were spent in the DC area. I root for all DC area teams.
While I might not care for the many insidious ways that BrainWashington DC permeates western culture, that does mean I can't still root for all the teams I did as a little kid/teenager.
Go Caps!
