The biggest factor with "chemistry" is having a line that lacks a balance of experience to offset new players.
The top programs replace linemen every year. When we have done it of late, there has been no depth and multiple new starters + lack of playing experience in game situations. I don't see that being an issue this season. I am not going to say that Fluker will be as good as a first round draft pick on day one, but he has more upside. Carpenter is experienced and a fantastic athlete. Vlachos will be more than serviceable (keep in mind he is beating out Cardwell).
When Nebraska was mauling people in the 90's, you never heard anything about them having to replace OL. Ditto for Miami and OU. We are just gunshy because of our recent experiences. The process is taking care of our gaps.
That's an observation I've wondered about all off-season. Especially considering OU is bringing in four of five new guys and still you see the lofty rankings.
Is it a pick and choose mentality from those who watch? Considering the lack of success you would think there would be more of a focus on Ole Miss and their losses on the line as well.
