I think the OL will be fine. I've heard good stuff about Formby, and I think he's going to surprise some people. Then we've got Brailsford, Proctor, and Roberts returning. This is year 3 for Proctor, and could be the year when he finally takes that next step. I've heard Jackson Lloyd may be ready to play also. Cubelic has been saying a lot that a huge chunk of the oline issues are due to the QB not sliding protections, and ever since then I've tried to keep an eye out for it, and sure enough, that is often the case. One of the biggest things that gives me optimism is when I go to the comment section of Milroe's Senior Bowl throws, and see "the offensive line is terrible". That's the same thing we said, so then I watch it and see several examples of protections not be shifted. I think our pass blocking may end up being a bright spot, because it's improved, and also because it may not have been as bad last year as it seemed.
I do wonder a little about our run blocking. I think some of those issues last season were due to wrong reads on read options and RPOs, but some of that may have been that the line was built for a power run team. That's a question mark, but hopefully it's more of the former than the latter.
