Independent from what has been posted in this thread, and without the benefit of analytical statistics to back me up, my 55+ years of being a football fan count as well. With no personal (or perceived) attacks intended or being contended with, I offer my opinion on GB's OL and the Passing game.
The first question to ask is, Has the GB OL been doing it's job to protect their QB Aaron Rodgers ?
The answer is not so simple as we would like to make it. The Left Tackle is maybe the best in the game at this point in time. Also, the Center and Left Guard have done very well. The level of play dropped off a bit with the Right Guard and Right Tackle positions. Bulaga has had problems with injuries and his play on the field suffered due to those injuries. In addition, the play at RG has not been that outstanding either. Furthermore, when replacements took over the RG and RT positions, the Right side of GB's O-Line suffered.
That said, GB's O-Line did do their required jobs most of the time. They allowed their QB the time to do his job. However, most know that QB protection is not expected to exceed more than a few seconds. As a result, if the QB is scrambling around, extending plays, holding onto the football, then there must be a good reason why. That reason is that his receivers are covered and they can't get themselves open.
Wide Receivers, Tight Ends, and even Running Backs depend on two assets to get open so that they become good targets for their QB. Those qualities being Speed, Agility, and/or both. IMO, the inability of GB's receivers to get open, was the #1 malady of the GB Offense. Injuries to inexperience to even poor play calling resulted in Rogers running for his life. The predictability of McCarthy's play calling also allowed opposing defenses to blitz at the worst times for GB.
With the healthy return of Allison, the gained experience of the returning WRs from their rookie seasons, and a less predictable offense should help elevate GB's passing game in 2019. Additionally, with healthy O-Linemen (and hopefully picking up a top new OT in the 2019 NFL Draft), the GB Offense should be in better shape.
One critical point however will be the TE position. Coach LaFleur's offensive system depends upon
blocking TEs. Jimmy Graham, who can't block, may need to be traded. Weather through FA or with the draft, GB will need a big, strong TE that can block and o yes catch too. The reason being that the running game is expected to gain in importance in the new offensive system.
Yes, I'd like GB to draft OT, then an Edge Rusher, and then... , but if it makes more sense to grab an Edge Rusher 1st, then they should go for it. I'm basically pointing at where I believe GB has needs. FA may well help fill need at the Safety and LB positions as well.
This is going to be a really interesting and challenging offseason for the Packers. Much will need to be addressed as we move forward. I just wish all of the Packer's organization super good luck as they enter into a new era of winning GB Football.
