Why did we trade for duckett?

[redskins5044]

this trade makes no sense to me we trade two draft picks for a guy who didnt even dress out last game. why make this trade i know portis was hurt and betts was a little banged up. i know betts is fa after this year but what i read in the USA today they also said duckett was a FA. if this is true we trade two picks away when if we wanted him to replace betts if he left we could have got him for free. and we arent using him right know he might walk after this season to another team. i just dont understand there moves sometimes in the front office. if we needed a player at any position we needed a another CB or O-lineman. This week is a big week for us to prove ourselves v.s. a good defense we need this win so i hope everyone that goes makes that place a living hell for leftwich.
