WMG: The Good Wife

The show takes place in the same world as Entourage.
Eli Gold is based on Rahm Emanuel, just as Ari Gold is based on his brother Ari Emmanuel. Obviously Eli and Ari are brothers, and the two shows take place in the same universe.

The show is heaven where the cast of The Wire are rewarded with a universe where the law is less corrupt.
It would explain all the familiar faces.
