Tex does have a point though. He was part of a line that protected Brees very well. Only 27 sacks even though Brees led the NFL in pass attempts. Also, Schneider has admitted that not keeping Evans was probably a mistake. Maybe the Seahawks offensive line is horrible because they've made bad decisions.
I realize he's probably not as good as Lang. I just don't think RG will be a huge factor. And you could certainly argue that Evans has a better chance of playing 16 games than Lang does.
