Campo, who was the Cowboys' coach from 2000-02, will also coach defensive backs.
He coached in college for 18 years before joining the Cowboys on Jimmy Johnson's staff in 1989. He's been in the NFL since, including brief stints with the Cleveland Browns and Jacksonville Jaguars before returning to the Cowboys in 2008.
Campo has three Super Bowl rings, and won a national title with Miami back in 1987, but struggled as a head coach. He went 15-33 in three seasons. Dallas ranked 23rd in the NFL in pass defense this season.
It's an interesting hire, if only because it's another very recognizable name. Weis and Campo share the distinction of flaming out at high profile jobs. Weis did so at Notre Dame. Campo did so at arguably the highest-profile coaching job in football.
They've both found new homes at a place that is anything but high profile.
Will they find renewal? Time will tell.
Either way, people will be watching.
