Carlito -- teaming with Santino right now puts him in two different angles going into WM24. 1st against Rhodes and Holly for the tag titles and 2nd being part of the Marella/Maria playboy angle

Shelton Benjamin -- I believe going to ECW and winning is called a push, so why would he want to leave now.

Charlie Haas -- I got nothing
