There aren’t many positive vibes coming from the Dallas Cowboys of late. After all, the team has lost three consecutive games by at least 20 points. But the Smith brothers – linebacker Jaylon and running back Rod – were among the few highlights in the Cowboys’ 28-6 loss to the Los Angeles Chargers on Thanksgiving Day. Jaylon led the Cowboys in tackles and Rod led them in rushing. Jaylon, the Cowboys’ leading tackler this season, was credited with eight tackles. He had one tackle for loss and one pass defensed. Jaylon particularly shined when the Chargers had a first-and-goal from the Cowboys’ 7 late in the first half. He tackled running back Austin Ekeler for a loss on first down, and broke up a pass intended for tight end Antonio Gates on second down. Los Angeles settled for a field goal. “Jaylon did some good things in the game,” coach Jason Garrett said. “He was around the ball. He was a physical tackler sideline to sideline. He showed up. He made a number of plays on the ball. “There’s no question he’s getting better and better.”
