Cubs going after Andy Pettitte?

[Andy]

He'd be the best (and probably most expensive) #5 pitcher in baseball. It would also give us a 2nd lefty. I seriously doubt it would happen, but if he were willing to lower his price tag. If he wanted to pitch again, I can't imagine the Yankees not signing him.

Now let's play in the imaginary world where the Cubs do sign him. Do you move Lilly up to 3rd to keep from having lefties back to back?

Zambrano
Harden
Lilly
Dempster
Pettitte

That's a roster that would make opposing teams cringe a bit.
