The author is wrong about the Cowboys not valuing Williams's position. It's one of the many perceptions that get formed in the media and then through repetition gets treated as fact, even though the evidence says otherwise. It's lazy and tired.

In reality, Dallas made a first round pick (Byron Jones) with the intent for him to play FS, which is where they put him after he got his feet wet as a rookie even though he looked just as capable of playing the very valuable CB position. It made actual major trade offers for Earl Thomas (a true FS) and Jamal Adams (a playmaking SS who was the closest thing one would find to FS value at SS). And Juan Thornhill was seemingly the runner up for Dallas's top pick in 2019, the one that went to Trysten Hill (also at a need position, DT, which is also a position the media loves to claim Dallas doesn't value).

In reality, Dallas values proven quality coverage guys at FS...but the supply of those outstrips demand, and many supposed strong coverage prospects there don't work out. The team WANTS to find a strong coverage guy at FS, but knows that it's hard (or otherwise expensive) to do just that. That's the reason behind the tweet in this article, that claimed that coaches all value FS big time but GMs don't. Don't be fooled...never mistaken a difficulty in getting what one wants to mean that one doesn't actually want that which is hard to get.
