I think the starters are very solid but I think depth is the question mark.
Assuming Anderson starts at one OG position that means that most of the back ups that can potentially contribute are walk ons (McGregor, Britt, Beckius). Although there is a possibility some RFr could contribute at tackle (Jacobs and Jerve), the fact remains the back up situation in the OL is very iffy, the product of yet more disasterous recruiting by Bohl.
