Agree that Buford had another pretty good performance, this time against one of the top front sevens in the country. There isn't much point in guessing why Buford is still a backup. In the larger picture, the takeaway is that Coach Yenser isn't getting the job done and needs to be replaced.
I don't give up on coaches easily.
I have addressed this final point before, but it bears repeating. There is a narrative circulating that we don't have talent anymore on our OL. That is patently false. Kiyaunta Goodwin was a borderline 5 star. Flax, Young, Burton, and Bingham were 4 stars. Buford was a high 3 star with an excellent Power 5 offer sheet. Stars aren't everything, but Cox was a midseason AA in 2021. Granted, some of these players are young, and some have changed positions. But those are coaching and developmental issues. Even if Yenser was the world's best OL coach, the exposure of these players to a new OL coach every year would still be an issue. But the observable evidence says that Yenser has not responded very effectively to problems this year. As I have suggested before, you really have to wonder what Goodwin is thinking. That subject actually scares me a bit.
