I don't think it constitutes to laziness just because someone else predicted it beforehand, lol. Actually, amnesia makes perfect sense given what Sabo had been through. Also, Oda doesn't need excuses, because he generally plans his story out way before time. I have every right to believe Sabo was created before the Marine Ford arc, and that he was not meant to be apart of the actual storyline until much after.
