Why are Jeopardy contestants so bad at sports questions??
“Bush League” is a term you may hear in the baseball world to describe something that is viewed as disrespectful to the game, cheap, unsportsmanlike, etc. Basically the “unwritten rules” nonsense.
It is not the name of MLB’s Spring Training league played in Florida.
That would be the Grapefruit League (and the Cactus League is in Arizona).
