And this...
While it's not technically wrong it always sounds off to me for the Indy 500 winner to be referred to as the Indy 500 champion.
...and subsequent posts. I didn't catch this remark, or who made it, but it's very unsurprising. The two terms are interchangeable amongst sportscasters. I don't like it either, but it is what it is.
Sportscasters here in the states are generally utterly clueless about motorsports, or any wheeled sport really. Since football, basketball and baseball are king here, they view the winner of the Super Bowl, World Series and NBA Finals as "champions", which is correct.
I've heard a good number of local sportscasters in various cities, and even those on national networks, state that they can't understand how someone who finishes a race in 10th can be the "champion" for the season. Similarly, I've heard the same for their lack of comprehending of how someone finishing well down in a Tour de France stage can still be the leader. This isn't because they are American, but because they are sportscasters
Perhaps the best comparison would be to compare them to a vacuous compere or presenter.
Never mind that the Super Bowl champion loses a few games during the regular season, or the World Series champion loses approximately 60 games a season. For some reason, once wheels are put on something, they can't fathom it.
