I certainly don't want to sound like the voice of doom and gloom here, but...
The line was definately better than last year - there has been some major improvement. Particularly in pass blocking. However, I'm still concerned with the run blocking. While they did open some holes, there were a number of times in which they just didn't get much of a push on the defense.
I still think we're a couple of years away from having a truly dominate offensive line. We got so paper-thin that we have not had the time to have guys mature within the system. It will come, but it's going to take time.
