It’s uncertain if the zone-read will become a permanent staple of NFL playbooks or if it’s a fad that be phased out over time. But Cowboys head coach Jason Garrett is certain it’s not going away anytime soon and that’s why his team is practicing how to stop it this week.

“It’s kind of a copycat league in a lot of ways so other teams will certainly see what those teams have done and probably make it part of what they do on offense” Garrett said. “So we have to be ready for it.”

The Cowboys already have had a taste. Last week in a 19-17 loss to Oakland in a preseason game Raiders backup quarterback Terrelle Pryor ran a variety of zone read plays gaining 31 yards on three carries and completing 6 of 10 pass attempts for 88 yards.

In 2012 Robert Griffin III and Washington helped make the spread-option scheme en vogue at the pro level as they beat the Cowboys twice and won the NFC East. This season Philadelphia’s new coach Chip Kelly is expected to feature the zone read in his offense.

“Teams are adding that into their game” linebacker Sean Lee said. “We have to be ready to defend it. We saw a little bit against the Raiders and it’s something we have to address now so we’re ready for it during the season. The more you prepare for something the better you play.”
