Worst case scenario for the Penguins in the draft?

Something popped out in a lot of mock drafts that have been out there, but in best graphical form on this one from The Athletic. The expected top-six is what it is (Schaefer, Misa, Frondell, Desnoyers, Martone) for players that can’t be expected to last very long. But a bad scenario pops up for the Penguins if the picks before them break like this.

Going down that list, each selection lands like a thud as center after center go off the board, and then the big defender gets swooped up one pick before the Pens are up to make their choice at 11.
