Mine's Leeds United. Last season was a heartbreaker (immortalized in this excellent documentary, free if you have Amazon Prime)(an earlier season in Leeds' history is the subject of the Michael Sheen film The Damned United), but this season is still very promising. It's funny that Leeds is exactly twice as old as the Blazers - it's their 100th season this year (and the fact that it's not being celebrated in the Premier League is enraging). I also think of their strip as white, because that's what was accentuated in their glory years of the 70s, just as I think of the Blazers' true color as black, because I came in in the Drexler years.
San Francisco 49ers - I grew up in the 80's and Jerry Rice is my favorite athlete of all time. Cincinnati Reds - I was a big fan of Eric Davis and Barry Larkin when I was a kid. This could possibly change if Portland gets an expansion team. Oregon State Beavers - I attended college there so am required to bleed orange until I die.
I used to be a big Nordiques/Avalanche fan, along with the NY Rangers. NFL - Packers and Raiders. MLB - Cubs and Dodgers. Those are usually the only other teams I follow.
Atlanta braves are my next favorite, a very close 2nd to the blazers. Then the timbers and the Cleveland browns.
San Francisco Giants (and for that reason @theprunetang is no longer on my Christmas list. Fucking Dodgers. Sheeee-it) and the Oregon State Beavers. And I’ll even cop to being a very fair weather Niners fan (not that I have much to get excited about for the foreseeable future).
Seattle Seahawks Washington Huskies Seattle Mariners and New York Yankees (I grew up a Don Mattingly fan and I like to follow regional teams hence two teams for MLB) Portland Timbers Chelsea F.C. (because of Pulisic) Edmonton Oilers for now Seattle NHL team
