>>Nets Fire Coach
One day after losing their fourth straight game, the Brooklyn Nets decided a change was needed. On Sunday, the Nets announced that they have parted ways with head coach Lionel Hollins and that GM Billy King will be reassigned within the organization.
"After careful consideration, I've concluded that it's time for a fresh start and a new vision for the direction of the team,” Nets Owner Mikhail Prokhorov said in a statement.
Hollins has coached the team for less than two seasons, getting hired after Jason Kidd left to coach the Milwaukee Bucks last summer. Under Hollins, the Nets won 38 games last season and made the playoffs but lost to the Atlanta Hawks in the first round. The Nets are currently 10-27 and are one of the worst teams in the league this season.
King has been the GM of the Nets since 2010 and under Prokhorov's direction, aggressively traded away assets to get players like Joe Johnson, Kevin Garnett and Paul Pierce. Prokhorov had a win-now type of attitude and King mortgaged Brooklyn's future to make this happen. Now after not winning anything, the Nets are left with a bleak future and no first-round draft picks until 2019.
Assistant Coach Tony Brown will be the interim head coach and the Nets are planning on keeping the GM job open until a replacement is found.
