The problem with our OL is that they are all originally mid-round selections. Pitts and Wand were both 3rd round selections. To improve, we need to invest first and second round picks.
This year, Jammal Brown-OT, Alex Barron-OT, Elton Brown-OG are the only three worth the 12th or 13th pick. I like David Baas, but he would be a reach.
I also like Ben Wilkerson-C as a third or forth round project. If not for his Oct injury, he would have been a first round selection.
