It is amazing how good or bad an OL may seem based on the quality of the QB and the playcalling.
I remember thinking the Patriots had a terrible O-line when Bledsoe was the QB and then it magically got better when Brady became the QB. Same thing with the Cowboys. Once Romo took over for Bledsoe, the Cowboys O-line magically improved.
We will obviously hit the portal hard for O-line. With competent coaching and QB play, O-line should not be a concern. If we bring back Freddie to design the offense, and Gio to leads it, you could have all Outland trophy winners along the line and they would still look terrible.
