Nick Underhill’s concern with Saints O-Line might be “heightened”

He didn’t speak of the backups…he is referring to the OL on the whole. He’s seen the Saints OL
more than anyone so I’m inclined to believe him. I also think he understands the importance of Penning, and though I haven’t done a detailed assessment, he has looked pretty bad at times this preseason.
He said he just finished the rewatch of the preseason game. Penning was the only projected starter who played.
