Sucks that none of the guys you listed were early enrollees as they could be getting some good reps this spring with a couple starters out. Van Poppel looks pretty mature and will probably have as good of shot as playing as a freshman as any DL ever will which is still not ideal. Maciejczak obviously has the brute strength but I have no idea what we should expect from him.Butler could be used interchangeably. Getting Riley Van Poppel, Maciejczak, Lefotu, Carroll-Jackson as big guys will help with some depth I would think. Goldman may also play defense but I think he will most likely play OT. A transfer at both lines would be very welcome. Especially another nose/big.
