John Wall is healthy and signed until 2019. And the lineup of Wall, Bradley Beal, Martell Webster, Emeka Okafor and Nene -- which, granted, played together for only 142 minutes -- outscored opponents by 27 points per 100 possessions last season. But Okafor, the team's best rebounder and defender, is out with a herniated disc. Nene will shift to the 5 but missed 48 games the past two seasons, and Kevin Seraphin is the lone backup big. That, Wizards fans, spells toil and trouble.
