The Las Vegas Raiders' instability has been well-documented. Except for defensive coordinator Patrick Graham. Originally brought to Las Vegas by Josh McDaniels, Graham stayed on for the tenures of both Antonio Pierce and Pete Carroll. CBS Sports' Matt Zenitz confirmed that Graham finalized a deal to become the Steelers' defensive coordinator on Thursday. So, it seems like the puzzle pieces are already being put together in Pittsburgh, meaning Graham's time in Las Vegas is officially over.
