Ran fifty yards for a touchdowm is this a complete sentence,,fragment or run on sentence?

fragment because it does not say I ran or you ran so it would be incomplete

It's a fragment. Do we have a noun? No, we need a noun before "Ran," such as "he, she, they, we"

(you didn't attach a copy of the poem, but i'm answering as best as i can)

since a simile compares two unlike things using like or as, it kind of gives an item the ability to do something it can't.

example: "the player was like a tiger on the field"

in this sentence, the simile conveys the idea that the player was fast and strong, like a tiger.
