You can think whatever you like, but there is actual proven value attached to games started together and average age for offensive lines in CFB. Obviously Kerstetter and Imade are gone after this season, as well as Okafor I assume, so there will certainly be at least 2 new starters next season.
Does that means Majors, Jones, Angilau and Karic are absolute shit and none of them will be starting next season as well? Maybe. At the same time, adversity leads to experience and experience leads to wisdom. Within teams of any sort, shared adversity leads to trust and trust can often lead to success.
The reality is that a 3rd year starter in Jones, a 4th year starter in Angilau, and a Jones/Karic with 1.5 seasons of playing starter snaps and another offseason might be the best 3 OL combo the program can muster with whatever other 2 additions are made.
Does that mean the staff shouldn't be hustling to find better fits? No. And they will chase guys in the portal and they'll land a few and we might get lucky and find one above replacement for the incumbents, maybe even two. But if we're heading into next season with the same offensive coordinator and the same OL coach, 3 of those 4 guys as starters won't be a cause for outright disgust at where we are as a program. To present otherwise assumes you do not fundamentally believe that both the player and the program are capable of any natural growth and development along the learning curve.
