There aren't a lot of lines that scare most people in the league, but that line is more than serviceable and could get the job done.
More than serviceable? I'm assuming serviceable means about average. We where near the bottom of the league in sacks with last years d line. So last years line wasn't " serviceable". Now with hardy gone, Gregory suspended for 4 games - even though he did little last year, Lawrence coming off of back surgery, how can this line ( as currently constructed) be any better? Even with Thornton, I would say we are about the same as last year which is near the bottom of the league in sacks.
I agree there aren't many lines that scare people. Hopefully we can get our line at least top 10 in sacks. I like your optimism though, and I hope we can make some key additions to our line.
