Because the Packers believe it will be tougher to huddle up and communicate verbally, they are relying on visual cues and signaling at the line of scrimmage in an uptempo attack.
"Coach made it clear from day one that we want to run as many plays as possible," Lang added. "Our goal is 75 plays a game. We had somewhere in the mid-60s last year."
The no-huddle fireworks left preseason opponents dazzled by the tempo and lethal proficiency.
"Man, they looked goooooood," Raiders receiver James Jones said two weeks ago, via ESPN.com. "They looked like they were in midseason form. A-Rod is the man in that offense. They're doing a lot of quick games, giving the receivers a chance to get the ball in their hands, make some plays for Aaron. But they looked good. They looked real explosive."
McCarthy is counting on a balanced attack, with the one-two punch of Eddie Lacy's smashmouth running style and Rodgers' superior arm and athletic ability making the difference. If they can get tone-setting Pro Bowl strong safety Kam Chancellor on a yo-yo instead of patrolling the middle of the field, they can succeed where Denver failed.
Here is what else has changed about Green Bay's outfit this year:
» The coaches and players have talked all offseason about fixing a defense that ranked in the bottom third of the league for the second time in three years.
"I say it a lot: We need to be accountable to our offense," linebacker AJ Hawk told NFL Media's Albert Breer this week. "We got Aaron (Rodgers) throwing the ball around. We got a ton of other weapons around him. We need to find a way to get some turnovers, get the ball back to them and kind of stand up as a defense finally."
To that end, the Packers have upgraded the secondary with the drafting of safety Ha Ha Clinton-Dix and an increased role for hybrid safety-cornerback Micah Hyde. They have a pair of breakout candidates at defensive end in Mike Daniels and 2013 first-round pick Datone Jones. They return All-Pro caliber pass rusher Clay Matthews and star nickelback Casey Haywardfrom debilitating injuries.
