Is that so? I was unfamiliar with football terminology so had to google it. Most references talk about "throwing a spiral" (noun), rather than "spiralling a football" (verb, transitive). But I can imagine this being a common usage. I have heard similar terms in other sports where you "verb" the ball, instead of throwing or bowling a "noun" :) So I presume when a player "spirals a football" it means the player imparts a spin to the ball. (As opposed to player moving his/her own body around the ball in a spiral path :) ) Whereas the HN title uses it in a slightly different (second) sense -- "magnetic fields spiraling Milky Way's black hole" meaning something like "magnetic fields moving around / orbiting the Milky Way's black hole" Semantics. literally.
