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

I understand it’s his job to weigh in, but is it supposed to be news that back up offensive linemen aren’t that good?
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.
