This is a bit of a different story from that of Dalton. The offensive line caused their quarterback to struggle as the pressure was brought constantly by the Packers defense. Each of the offensive linemen had missed reads or was just blown up by Packers defenders. Whitworth probably had one of his worst games in recent memory. He has not played solid of late, but he is a professional and should be hitting the film room hard to try to figure out what he has been missing.
Another veteran offensive lineman that struggled mightily was Andre Smith. For having such a big body, he was moved with ease by Packers defenders. Smith needs to keep improving and developing his fundamentals going forward into the regular season.
Guards Clint Boling and Kevin Zeitler struggled as well both in the run game and in pass protection. Keep this in mind though; one of these guys is a rookie and is still just learning the way the game is played in the NFL. When Clay Matthews blew by him in a heartbeat, chalk it up to a great learning experience for him, as he will be sure to not allow that to happen on a routine basis. Boling is also trying to get his feet wet in the Bengals starting lineup. He has only been running with the ones for a short time after Travelle Wharton was lost for the season. He is another player that will need some time to develop.
So, sure, things look choppy for the offensive line right now (to put it nicely), but keep in mind that the Bengals have three savvy veterans that are able to quickly learn from their mistakes and two younger guys who are doing what they can to adapt to this game as quickly as possible. It may take a little bit of time yet, but the offensive line should turn out to be one of the most improved groups as the season begins. If you have your finger on the panic button here, be patient as there may be no need to press it by the regular season opener.
