PITTSBURGH — Shortly after Germie Bernard arrived at training camp in Latrobe, Aaron Rodgers pulled the rookie receiver off to the side. In no uncertain terms, the future Hall of Fame quarterback laid out his expectations.“If you want to be able to play with me, these are the things that you need to know,” Bernard remembers Rodgers telling him. “You need to learn how to think like this. You need to know what to do after this. You need to know what to think in these circumstances.”A self-described perfectionist, Rodgers has a detailed and demanding approach that is part of why he’s won four MVPs and a Super Bowl. It’s also why young receivers have sometimes struggled to make an impact. Davante Adams felt some of that early in his Green Bay days. Roman Wilson absorbed it often last year, as he tumbled down the Steelers’ depth chart and, eventually, off the game-day roster.Rodgers expects receivers to be where they’re supposed to be when they’re supposed to be there. In a true West Coast offense, the depths of the receivers’ routes are married to the steps of a QB’s drops. Rodgers explained this offseason that a QB should be able to throw the ball blindfolded.“It’s really made me home in (on) the smallest details,” Bernard said. “He’s very detail-oriented. It made me dive deeper into my playbook, dive deeper into my relationship with him, so I can start to understand the way that he thinks.”Will the Bengals eclipse the Ravens for the AFC North title?Mike DeFaboA versatile receiver, Bernard has the skill set to line up at all three positions: X, Y and Z. The Steelers have asked him to learn all three positions so he can move seamlessly around the offense. However, getting on the field early goes beyond just knowing the plays in the playbook.Coach Mike McCarthy said this week the team isn’t going to have a “black-and-white, run-it offense.” They’re going to lean into their quarterback’s experience and give him plenty of latitude to get the team into the right plays at the line of scrimmage. For Bernard, that means deciphering hand signals, being prepared to run the second or third play that’s called in the huddle and adjusting routes on the fly based on coverages.
