When backup Vikings linebackers were struggling on defense and special teams during the preseason, co-defensive coordinator Adam Zimmer said the "train is leaving" to convey the urgency he wanted to see from the position.
Nick Vigil, Blake Lynch and company caught the train, easing concerns about the position's depth just as it nears full strength. Vigil, the sixth-year journeyman, impressed in his four starts for linebacker Anthony Barr, who was a full participant again Thursday ahead of his expected return Sunday against the Lions. Barr will return to his full-time role, moving Vigil to just weak-side linebacker duties in the base defense.
