Zambrano going back to Tampa Bay?

At Rotoworld, they write about Victor Zambrano and him possibly signing with the Devil Rays:

The Rays have discussed a minor league deal with free agent Victor Zambrano.

Scott Kazmir and Zambrano in the same rotation? According to the St. Petersburg Times, Zambrano may have superior offers. Still, other than the Nationals, there isn't a team in baseball in better position to give him a rotation spot.
