Another BJax question

[Picksburgh]

My Rbs are looking healthy and I need serious QB help with Kolb out, I have the 6th waiver right now should I try and grab BJax or wait with it and keep what i have and upgrade . Or I can grab Spiller who was just dropped

QB - Kolb

WR - Moss, Colston, Bowe, MWilliams, Floyd

RB - Mendy, Best, Forte, MBush, FJackson, Caddy

TE - Zmiller Olsen

D - Miami (weekly)

IDP - Pozluzny (weeky)

K - Rackers


If I grab him it will be for trade bait to upgrade my QB/TE position and I could grab Garrard, Hasselbeck of FAs hopefully
