Obviously records make no difference for the preseason. Win-loss is irrelevant.
What can be gained is learning from successes and failures. Like having great two minute drills, Redzone success offense or defense, Clock management, Bouncing back from and dealing with adversity.
Players who show flashes now might get a chance later in the season because of injury or just to keep a player fresh.
But win and loss obviously means nothing until the regular season starts, And even then it’s only about playoff positioning. The great teams are going to get through the regular season and position themselves as highly as possible for that playoff run, while hopefully getting some rest for overworked players along the way.
