NBA Commissioner Adam Silver said Tuesday that the league might look at ways of maintaining competitive balance following Kevin Durant's blockbuster move to join the Golden State Warriors. Silver expressed concern at the signing which creates another super team and indicated that the NBA's parity might be better served if changes were made to the collective bargaining agreement. "Just to be absolutely clear, I do not think that's ideal from the league standpoint," Silver said of lopsided teams during a news conference at the league's annual board of governors meeting.
