LOS ANGELES -- In case it wasn't obvious enough by the situation -- fourth-and-1, one-score game, start of the fourth quarter, ball near field goal range -- Mark Barron confirmed it right before the snap. The veteran inside linebacker saw Dallas Cowboys wide receiver Noah Brown go in motion and set up right behind tight end Rico Gathers, a dead giveaway that an inside run was coming. The Los Angeles Rams' defense had spent the entire week focused almost exclusively on containing Ezekiel Elliott, simultaneously fighting the incessant notion that their star-studded unit was generally inept against the run.
