21st Century Big Four Sports Champions

Name all the MLB, NFL, NBA, and NHL teams that have won a championship since January 1st, 2000.
Based on the date of the championship game/series, NOT the dates of the regular season
I am aware that the 21st century officially started on January 1st, 2001. I officially don't care.

I realized after I created this quiz that it is essentially the same as https://www.jetpunk.com/quizzes/north-american-sports-champions-since-2000, so I'm not going to bother updating this one. Go to the featured one instead :)
