Eli5 why in football do they always reference rest as beneficial to the defense?

Question

So watching college football today the announcers always make a statement like “That drive took 10 minutes so the defense got a good rest”. How is that rest only beneficial to the defense and not for the opposing offense?

Answer 1

A very simple way of putting it is this:

If you put X effort into trying to do something, it generally requires more than X effort to stop you.

Defense simply has a higher energy requirement, and thus benefits more from rest.
