TE pick up...now?

[ECG77]

I need to pick up another TE for my week 5 replacement for Witten. Reason I'm picking one up now is tight ends in my league are slim pickings. Here are the tight ends I'm looking at for week 5.

Tony Gonzalez vs GB
Scott Chandler vs PHI
Jermaine Greshem vs JAC
Jeff King vs MIN
Brent Celek vs BUF
Tony Scheffler vs CHI
Zach Miller vs CIN

Fred Davis is available but unfortunately has the same bye week as Witten.
