I don't know where people are getting their thinking about the OL.
Yes, Frazier looks like he can be a 10 year starter at C, and that is great.
But even that this OL is less set than it was this time last year. Jones was very bad most of the season and likely penciled in at LT. Gave up like the third most sacks for OTs in the league and the hope is moving him to LT will fix him?
Fautana has talent, but had little pt in college due to being hurt before losing his rookie year to being hurt.
McCormick showed some flashes as did Anderson.
But a lot has to happen for this line to simply not be a disaster next season.
