Who exactly are you quarreling with ? lol.
Nobody! But thanks for asking. I'm just referring to the comment made by LeFleur, about guys being played sparingly, until they can handle the work load. When I suggested it a few of our members decided that wasn't how it's done, I pretty much didn't know what I was talking about.
Having coached, I know damned well it takes time to rebuild the stamina you need to play every down. You don't take that final step in practice, it's done in games. That's why you transition players back into the lineup, you don't just throw them in.
While you're going through this transition, on defense, you need to protect your weakest links on the field, by modifying the assignments, and offering double coverage where needed, to protect weaker defenders. As an example, Jaire can be counted on for single coverage as a corner back, but you need to provide assistance over to top, or underneath, for most of his replacements, when they're playing extended periods of time. They just don't have the coverage skills.
When you do that, your primary play has been changed, and you essentially become a bend but don't break defense to protect yourself against the large chunk plays that can create easier scores against you.
It's pretty simple, and it's what you have to do. It's just common sense.
But, that's my opinion. What would I know.
