NBA general managers met on Wednesday in Chicago at the pre-draft combine.

Two topics the GMs discussed are the date of the trade deadline and the buyout/waiver process.

Players must be bought out just a few days after the trade deadline to become playoff eligible.

Deron Williams, Andrew Bogut and Matt Barnes are just a few of the players that were bought out in late February to join title contenders.

The NBA previously changed a rule to prevent teams from using their own players to help facilitate a trade and then re-sign them once they're waived. The Cavaliers used this loophole in 2010 to trade for Antwan Jamison and then re-sign Zydrunas Ilgauskas.
