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 couple of other points:

1 – the offense usually has a more rigorous conditioning program

2 – the Dlinemen are actively trying to get around or through the Olinemen so they have to work harder and will tire sooner unless rotated. You typically don’t rotate Olinemen.
