UnGoogleable Research – What I Already Know

My focus question is Why can't high school basketball players just jump to the national basketball association? The reason why I wanted to know that is because I don't agree with the rule about high school player can't just skip college to go to the National Basketball Association because I think the basketball athletes should have a chance to show their potential against legends. I also don't agree with it because the last person that they let skip college to go to the national basketball association and that player was Kobe Bryant and they let Andrew Bynum into the nba at the age of 17 but why would they just stop player coming in from high school. I think but at the same time I know why they are doing that because they want high school students to get a taste of what it's like to play in college before getting to the nba. They also let Amir Johnson from westchester high school in 2005.
