Trade Deadline

[Keyser Soze]

My fantasy league's trade deadline is today.

My roster is as follows:

QB Chandler
RB Dunn
RB Rudi Johnson
WR Harrison
WR Holt
TE L.J. Smith
D Cheifs
--------
BENCH
QB Garcia
RB Betts
RB Candidate
RB Dillon
WR Mason
TE Crumpler
D Saints

Do I trade Holt or Harrison to get a back?

I've been offered Tiki/Porter for Holt/Dunn. Any suggestions for reasonable offers I should put out for a back?
