Odysseus' Ego

What would have happened if Odysseus had not told his name to the cyclops Polyphemus? Would he have had to go against Poseidon? Could he have made home to see Telemachus and Penelope before the suitors started to eat him out of house and home? Would the rest of his men made it home? The reason that Poseidon learns of Odysseus's name is when he brags to Polyphemus that the the name of the who defeated you is Odysseus. The cyclops calls on his father and tells him to curse Odysseus for hurting him. The ocean would not have tried to sink him as often as it had. He might not have had to run into Circe, Calypso, Scylla, Charybdis, or the sirens. However on the other side of the argument there might not be mentors. If Odysseus had made it home the reason of Athena coming to Telemachus as Mentor would be nonexistent. Where would the term Mentor come from?
