What happened: Dallas Cowboys defensive coordinator Christian Parker emphasized eye discipline ahead of facing the San Francisco 49ers. Parker noted that defenders must identify where players line up when the ball is snapped rather than reacting to misdirection, cautioning against "chasing that rabbit all day.
Why it matters: San Francisco's heavy use of shifts forces opposing defenses into split-second communication adjustments before the snap. For Dallas, maintaining gap integrity and assignment-sound coverage will determine whether the unit can neutralize the 49ers' perimeter attack.
By the numbers: San Francisco holds the NFC's top record at 7-1 following a 38-17 win over Las Vegas, while ranking first in pre-snap motion rate. Dallas enters at 4-5 after defeating Indianapolis 27-23 on Nov. 8.
What to watch: Dallas prepares for Sunday's matchup against San Francisco, aiming to counter the 49ers' shifting formations.
