Witten out now who do I Drop

Ok so i dont have a back up for witten and i have no idea who i should drop to pick up a back-up for a week. Its a ppr league. Heres my team, let me know what you think. A few of the Te's available are Gresham, H Miller, Dallas Clark, Greg Olsen To name a few.

Qb A. Rodgers

Wr. R. White, Mike Wallace, Bowe, Stevie Johnson

Te Witten

Rb J Stewart, Benson, Helu, McGahee, B wells, BGE, and Piere Thomas

k Kaeding

D Baltimore

I would drop Thomas, he will be battling Ingram and Sproles for touches, if not, drop Helu as the Redskins backfield is packed and I like Royster over Helu.

I would pick up Gresham, but make sure he is healthy...if not, Olsen.
