re: How good can this offense be?

the o-line can be good next season. The talent is there. May just need to shuffle some players around to get the best 5 on the field at the right positions. OBJ and Landry are both good recievers but boths talents are better suited to slot reciever. So one or the other should start, not both, along with Quantavious Leslie if he makes it here, if not then Boone, Wright, or Dural. Dickson makes throwing to the TE a good option. Copeland should be even more of a beast at FB. Hopefully Blue is back to full strength as he is a good change up to Hill. It's not like the cupboard is empty. Cam has enough to work with to make this a good offense IMO.
