Semantics
these words are synonyms, if you thought I literally meant Elam fell to the ground then you are sadly mistaken. One should not have to explain literally if you saw him falling all over himself, slipping, stumbling, tripping with no contact from the WR. The WR didn't run some devastating route with a fake, quick cut or double move. It's absolutely Elam's fault if you have man coverage with a slot WR and you never touch or impede the WR on a go-route then who knows else's fault can it be. Even if you want to give Weddle some percentage of blame then Elam still gets a bulk of the blame for his poor play and error!
