Need help with my QBs, please (Dropping Kolb)

[StephanP89]

Here's my roster:

QB - Matt Schaub
WR - Calvin Johnson
WR - Greg Jennings
WR - Hakeem Nicks
RB - Chris Johnson
RB - DeAngelo Williams
TE - Kellen Winslow
K - Lawrence Tynes
DEF - Chiefs

Bench:
QB - Michael Vick
RB - Arian Foster
RB - Brandon Jackson
WR - Mike Wallace
WR - Malcolm Floyd
TE - Owen Daniels

Dropped Kevin Kolb for Jackson, taking in Vick. Hope that's a smart move.

But, these are the top QBs available:

David Garrad
Matt Hassalback
Josh Freeman
Vince Young
Derek Anderson
Trent Edwards
Jake Delhomme
Jason Campbell
Matt Cassel

Should I keep Jackson for bait for a better QB now that he's the hottest draft pickup from this morning's news or horde him so nobody else has him?

What should I do?
