They only have 5 players: Kobe, Gasol, Odom, Fisher, and Luke Walton.
The issue isn't that they were missing Bynum. It's that they weren't willing to pay role players like Shannon Brown or Sasha Vujacic, or end of bench guys like Adam Morrison and DJ Mbenga.
Prior to this season, Josh Powell (10th man) reached out to 2K about being in the game, and never heard back from them.
