Spiller for which of these receivers

Andre Johnson (not happening)
Stevie Johnson
Mike Wallace
Malcolm Floyd
Mike Williams

I have Richardson and Sproles starting with a waste of a roster spot in Ingram.. Need another back in case one of my starters goes down, this is more of an insurance move.

I already have a stable of receivers and was offered Spiller. Need to pull the trigger before I find myself in a bind.

Pierre Thomas is also on the table from someone else but I prefer Spiller.

So who is the most reasonable offer?
