Rasheed Wallace is a fascinating case study of talent versus want. Wallace averaged 14.4 points per game and 6.7 rebounds per game.
However, he was a 4 time all-star, a one time NBA Champion. But he made you feel like he just left much more on the table.
He seemed to never put all his talent together to reach his full potential but was always known as one of the most talented players in the NBA during his time.
