Williams comes to Dallas with a familiar face already on the sidelines. Cowboys defensive line coach Aaron Whitecotton spent time with Williams in New York. Whitecotton was the defensive line coach for the Jets from 2021 to 2024. Those years also happened to be when Williams earned all his Pro Bowl selections and his All-Pro season.

It was a busy NFL trade deadline for Jerry Jones and the Cowboys.

I can’t imagine that there has ever been an instance of brothers being traded from one NFL team to another in the same transaction.
