After the Dallas Cowboys lost to the Seattle Seahawks in the early parts of the season, wide receiver Doug Baldwin claimed that Seattle knew the Cowboys defensive hand signals.
According to Rams guard Austin Blythe a similar thing happened on Saturday night. Los Angeles knew what the Cowboys defensive line was going to do “Plus-90 percent” of the time. That’s likely part of the reason why the Rams had so much success on the ground. From The Ringer:
Depending on the alignment of the Cowboys defensive tackles, particularly whether Maliek Collins was shaded closer to the tackle instead of the guard, the Rams figured a stunt may be coming.
