You are saying what I wanted to say. Pretty much, I think the QB play has improved quite dramatically, while the line play only improved a little (And actually regressed a tiny bit in the run blocking department).
For me to think that the O-line play has improved, I'm going to want to see the QB Hurries, and the QB Injuries down just a bit. I know we were like 7th in the league in sacks given up, but don't think for a minute that Salaam did not routinely get beaten by plenty of DE's this year is only kidding oneself.
Honestly, I don't see how anybody could think that our O-line play improved so much that we shouldn't worry about it at all. I think it's a top priority, especially with the Weary, White, and McKinney injuries.
I do like all of the centers that we have picked up recently, and I hope that the competition means we will get a better quality center starting next year.
After looking through most of the drafts, it seems the experts have us pegged for picking either Stewart or Mendenhall (More Stewart than Mendenhall though), or maybe an OT. The mock that has us picking up Godser from Boston College is just flat out wrong. Godser is pretty much a RT no matter how you slice it, and I do not think that will be what we get in the 1st round.
Honestly, I think the drafts that have us taking some defensive player are going to be the ones that are more correct for us. I also think that BPA and all that will play a factor.
