Players like Kevin Durant, Blake Griffin and LeBron James garner a tremendous amount of attention, and it is well deserved, since they have met or even exceeded the expectations which have been set for them.
However, there is another group of players in the NBA that receive a tremendous amount of attention and turn out to be all "sizzle and no steak." These players include Ricky Rubio, Rajon Rondo and a bunch of others as well.
Gauging talent in the NBA is an exact science and takes a number of factors into consideration. Figuring out how great or unspectacular players will turn out is no easy task.
These players may even turn out to be good players, but overrating them can be costly for teams who are counting on them to be franchise saviors such as Ricky Rubio for example.
It is much easier to become enamored with a players raw talent, rather than face the facts and realize that he is not a "game changer" or "franchise player" but rather a role player or even a bust waiting to happen.
