What do we do in this scenario?

Let's say that after week 17 the Bengals are in the playoffs and their seeding is already determined meaning that, like last year, the last game of the season against the Ravens doesn't mean anything. But let's say that the Ravens are playing for a playoff spot, win and they're in or lose and they're out. Do the Bengals still rest the starters or do they play to win to keep the Ravens out? I know this scenario isn't likely to happen but it's fun to contemplate.
