I'm in a real-player sim league that's about to undergo an expansion draft. Each owner is allowed to protect five players; then one is selected and five more can be pulled back. My most valuable players probably are:

Carlos Zambano
Noah Lowry
Tomo Ohka
John Patterson
Aaron Heilman
Cory Lidle
Clint Nageotte
Billy Wagner
Ramon Hernandez
Carlos Delgado
Ryan Freel
Vernon Wells
Ken Griffey Jr.
Willy Mo Pena

So which five of those guys should I protect?
