Any sport, in the same year/season.
I hear this at least once a year, esp in football (gridiron) and basketball, usually by overzealous college fans.
"The undefeated Alabama Crimson Tide are so good this year that they could beat the winless Cleveland Browns!"
This strikes me as bullshit.
But maybe I'm wrong.
Sports fans (of any sport that has organized college and pro leagues), are there any instances where you would actually take the best college squad over the worst pro team in the same sport in the same year?
