Terrance Williams needs to answer a very important question, and he needs to answer it now: what exactly does he do for the Dallas Cowboys?

Is he a sure-handed possession receiver? Unlikely. He had two big drops last week against the Rams, and Sunday against the Packers he was responsible for Damarious Randall's pick-six. Any hopes that the team had for him complementing Dez Bryant's size with steadiness seems to have disappeared completely.

Speaking of size, does Williams have it? Could he be a dangerous red zone target? He hasn't been this season. He has zero touchdowns, and the Cowboys could use some extra help in that area. They entered Sunday's game ranked 14th in red zone touchdown percentage. Last season, they were fifth.

Does he have the speed to be a deep threat? Considering he has gained less than ten yards per reception this season, that's not likely. His longest play of the year is 23 yards.

So, I'll ask again: what exactly does Terrance Williams do?

We know exactly what Brice Butler does. He has one skill and one skill only: making plays down the field. He does it remarkably well. He now has four plays that have gained 30 or more yards this season... and those represent half of his total catches. That skill is remarkably important for a team that needs to convince opponents that they are willing to push the ball in order to create space for a running game that has been lacking this season.

You would think that would create more opportunity for Butler, but he has never received as many targets in a game as Williams this season. Against the Packers, he caught a huge 49-yard bomb from Dak Prescott that kept their opening drive alive... and then he was put on the shelf for the rest of the game until the final play.

Butler has been marginalized, and there isn't a good reason for it. He opens things up for the running game, and he makes big plays. That is a specific skill set that is not offered by any other current Cowboys. The Cowboys don't need Williams to be a steady possession receiver, that is what Jason Witten is for. They don't need him to run shifty underneath routes either, because that is Cole Beasley's job. Dez Bryant is the big physical receiver.

Butler is the player that complements them. Williams does not. And unless Williams can prove he has value in some other area, that he legitimately helps his team's offense in some way that we aren't currently seeing, then he should be benched for Butler.
