Is Duchscherer worth a roster spot?

[drunkmonkey]

10-team 5x5 H2H league. My DL slots will be filled with Lackey & Hoffmann to start the season. Here's my current pitching staff:

SP
John Lackey (headed to DL)
Josh Beckett
Roy Oswalt
Carlos Zambrano
Gil Meche
Jordan Zimmermann
Justin Duchscherer (headed to DL)

RP
Carlos Marmol
Matt Capps
Huston Street
Carlos Villanueva
Trevor Hoffmann (DL)

When Lackey is placed on the DL, I'll be able to add another SP. My pitching is kinda weak, should I drop Duch to pick up another SP? Or is he worth holding on to?

sample of available SP:
Jonathan Sanchez
Oliver Perez
Mike Pelfrey
Joe Saunders
Chris Volstad
Wandy Rodriguez
Kenshin Kawakami
Mark Buehrle
Andy Pettitte

I would drop Duch and pick up Pelfrey. I am high on Pelfrey this year and Duch may still be available by the time Hoffman is off the DL.
