The NBA Draft is entirely different than the NFL one.
Oftentimes in basketball, the very top prospects have been identified for a draft entering their one year of college, overseas, or in the NBA's G-League. Everyone knew LeBron James would end up phenomenal as an NBA player in high school, and one year at Ohio State wouldn't have changed that.
As a result, there's not really a ton of drama with most NBA Drafts. Instead of a wide net of players that could go at a multitude of positions of need, the top teams in the lottery are often choosing between a very small contingent of top prospects, and talent gaps between picks can be enormous.
