He ___________ football game.

The phrase "Almost never attends" is the most grammatically correct and natural-sounding way to express the idea that he rarely goes to football games. In this structure, "almost" modifies "never," indicating that while he does attend sometimes, it is quite infrequent. This placement emphasizes the frequency effectively, making the sentence clear and easy to understand.

The other structures are awkward or confusing in terms of standard English usage. For instance, "never almost attends" disrupts the flow and clarity, while "almost attends never" is not a typical arrangement of words in English. "Attends almost never" is also less common and may sound a bit off, as English speakers typically prefer putting the adverbial phrase before the verb to ensure a smoother rhythm and comprehension.
