After looking at the 19- and 20-year-old rookies, typically guys who played just a season of college ball, we will examine the 21-year-olds, who fit in the "sweet spot" of having played two seasons, or perhaps three, of college ball. These are guys who entered the draft after either going back to school to improve what was already a decent draft stock, or because they would not have been drafted the previous June. This ranking is based on what each player would look like if he fully realized his potential, whether that is likely or not.
