As a football/soccer fan myself, I half agree. I would guess that most people don't know half of the MLS teams, let alone which ones were champions. Also, MLB, NBA, NFL, and NHL are considered to be the 4 main North American sports leagues, leaving out anything soccer related.
As a soccer fan, I would say you're more likely to have people who know nothing about soccer score higher on a UEFA Champions quiz than have an average soccer fan score high on an MLS section
27/39...I don't feel bad for not getting all of them, since hockey is the only one I really follow (and I did get all of them), but I should have gotten the Spurs. I don't care much for basketball, but the Spurs have won enough to penetrate the fog of apathy for that sport. Should have had that one.
If you count the Warriors for the 16-17 season, then you most certainly should count the Eagles as a 2018 team, move every NFL team up one slot, and insert the Ravens for 2000.
I was so looking forward to typing Raptors and getting to see a Toronto sports franchise in a champions quiz, unfortunately it doesn't have the most recent champions quite yet.
How is it the Braves are so far down the list after winning just last year? More people guessed the White Sox, who haven't won since 2005, than the Braves.
GO WARRIORS!
