Perceived depth in football can change very quickly. Wasn't that long ago it looked like the Packers were set at CB with Jaire, Rasul, and Stokes. Now it's seen as a need. If you have a chance to draft what you think is a great offensive lineman, it's not a bad idea. Having a great OL has been the key to the resurgence of the Lions. It's made Jared Goff a much better QB.
