Robert Saleh (SAH-lah) is in his 14th NFL season and second as the 49ers defensive coordinator.
In 2017, Saleh led a 49ers defensive unit that allowed 5.28 yards per play, which was a 0.62 yards per play improvement from 2016 and the third-largest improvement in the NFL from 2016-17 (Cle. - 0.76 yards per play; NYJ - 0.72 yards per play). The defense also finished the season holding their opponents under 100 yards rushing seven times. From Weeks 12-16, the 49ers streak of holding each of the five opponents under 100 yards rushing was tied for the longest streak in the NFL over that span (Arizona). It also marked the first time the 49ers held five straight opponents to under 100 yards rushing since Weeks 11-15 of the 2012 season. The 49ers defense was among the league leaders at getting into the opponent’s backfield on running plays, finishing ranked tied for fifth in the NFL by forcing 53 rushes for negative yardage.
