How does the draft work?

The NBA draft sees teams take turns choosing college players. Teams take turns subject to the order of their alloted picks. 

 There are two rounds in the draft. Both rounds have 30 picks, so there are 60 picks in total in the whole draft. 

Each team gets one pick per round, unless, like the New Orleans Pelicans and the Atlanta Hawks (both in the top 10), a team has acquired multiple picks in a round.  

Picks are incredibly valuable as teams chase the country's best young talents and they can regularly be traded for players already operating in the NBA.

While some teams may have a host of picks, others may not pick at all if they have traded away their draft options.

On May 14 the order was revealed in dramatic at the NBA Draft Lottery.

League commissioner Adam Silver is trying to eradicate 'tanking' - where teams deliberately hit poor form in order to better their chances in the draft. 

The balls spun around the machine and revealed that the New Orleans Pelicans will have the top pick in the 2019 draft.

Memphis Grizzlies will pick second, New York Knicks are to choose third and the Los Angeles Lakers were awarded the fourth pick (before it was traded this week for a top five player). 

Cleveland Cavaliers will hope to snag a gem at five while Phoenix Suns, Chicago Bulls, Atalanta Hawks - who have the eighth and tenth picks - and the Washington Wizards complete the top 10.
