That's a possibility but Larry Brown didn't like rookies or young players in general. He was the coach of the 2004 Olympic team that got the Bronze that had Melo, Lebron, and Amare. The younger guys were basically glued to the bench. Lebron averaged 5.4 ppg, Melo 2.4 ppg, and Amare had 2.8 ppg. Brown did not play them much, at all. Emeka Okafor was there also and only saw time in 2 games but didn't score at all. Melo only played in 7 of the 8 games. Everyone else played in all 8 games but I can't find the minutes they played, their scoring says how little though.
