Exactly, just worry about getting there. If there's a couple days to go in the season and you have nothing to play for (division, home field wild card game), then I would expect them to basically shut down the better part of the pen for a few days. Example, they go into Detroit for the last 2 games of the season with the home wild card game clinched and the Cubs already won the division, then Hader, Knebel, Soria, and Jeffress are not pitching in the last 2 games under any circumstances. But all the starters are pretty close together and I'd expect they'd go with whoever is up and plan on handing it over to a fresh pen early.
