With two hours left before the deadline, there’s a whole lot of optimism coming from the Simmons camp. Does that mean the deal sending him from Philly to Brooklyn will get done? No, but it’s certainly notable. As a source close to Simmons who expressed this confidence put it, the only thing that might mess this trade up now is “ego” on the Nets side of the equation. On one side, you have a three-time All-Star in Simmons who could help salvage Brooklyn’s reeling season while rehabilitating his image that has been so tattered over the past year. On the other, you have a player in Harden who has suddenly become a (rapidly) depreciating asset.
