The Facts: Watt is signing with the Steelers, Ian Rapoport of NFL Network reports. He’ll join his brother, T.J. Watt on the Steelers.

Diehards Line: Next season they’ll face their other brother, J.J. Watt, when the Steelers play the Texans in the regular season. Derek Watt plays a less important position than his brothers, but he’s a good fullback and a good special teams player. Last year Watt played 79 percent of the Chargers’ special teams snaps and 12 percent of their offensive snaps.
