I said that neither will ever have the overall stat line for a season that Duncan has. That is 25 ppg, 13 rpg, 3 bpg, 4 apg. I've already said that Amare can score like Duncan and that Howard can rebound like Duncan. Neither is anywhere close to those numbers though. Amare is averaging 1 apg and 1 bpg for his career. Duncan has been on the All NBA Defensive team every year he's been in the pros. Let me know when Amare has his first okay. I'm talking about all around game, Duncan is a better defensive player.
Oh and about Amare being with a good rebounder in Marion, Duncan had David Robinson (pretty good rebounder) for the start of his career and was still averaging 12 rpg from the start. Amare needs to hit double digits in average rpg before he's even in the discussion.
