I think this is a good take. That's one reason I think Veritas is flawed in his view that the defense is going to regress based on the starters we lost. He says if the backups were as good as the starters they should have been starting last year. I think the older player typically gets the nod even if the younger guy is slightly better. Just out of respect and the expectation that the more experienced guy will make better on field decisions and fewer mistakes even if less talented physically.
I'm not sure if I agree with this. We've seen plenty of older players with a history of getting time lose reps to better, younger guys. However, I do think that it's easy to discount the improvement a player can make over eight months in the off season. Just because a back-up wasn't better than the starter in the fall of 2019 doesn't mean they won't be better than that player was in the fall of 2020.
