2010: DeMarcus Cousins -- No. 5 overall
Cousins earned First-Team All-Rookie honors in 2011 after averaging 14 points and 8.6 rebounds per game. His numbers improved to 18 points and 11 rebounds per game in 2012, and slightly dipped this past season when he averaged 17 points and 10 rebounds per game. He is so talented that many critics and analysts alike believe he can be one of the top big men in all of basketball. However, he is also widely considered one of, if not the most immature players in the league, and has had several altercations on and off the court that have led to suspensions. He is eligible for a contract extension this summer, and several media outlets have reported that if he doesn't get a max deal, he will demand a trade.
