This is the sort of question that happens when your entire view of Nebraska football is viewed through the prism of Keep Frost or Fire Frost. Nowhere in the article did I say anything pro or against Frost, keeping or firing.
@N_trepid didn't say anything obvious in the OP either. I talked about the O-line. Why are we incapable of just talking about the O-line? Yes, Frost is the head coach, but he isn't integral to discussing whether or not our O-lines have been veterans or newbies in the past few years. He isn't integral to discussing how well (or not) Coach Austin has done at developing them.
If you really, really, really want to focus on head coaches, etc., how about doing a deep dive into all of the O-linemen who Riley's staff left behind for Frost's staff to develop. The cupboards were incredibly bare. Did you read the article? If it takes about 3 years to develop O-linemen, and the good ones that we had either graduated after one year (Farmer and Foster) or were only sophomores in '18 (Jaimes and Farniok), what SHOULD you have expected from the O-line up to this point?
Here's another mini-assignment for anybody who cares: Let's compile a list of new coaching staffs that were instantly successful when they inherited precious few O-linemen who could compete at their league's level. I'm serious. I would like to dive into any of those coaches' teams to figure out how they did it... if they exist.
