Could be waiting on the Raiders signing Freeman, making Matt Flynn available for trade.
They don't practice until Monday, I believe, so there really isn't anything that the new QB can do until then anyway. Also, whoever they bring in will be running a limited playbook which won't be much different to what we were running with Manuel at QB.
IMO, our options, in order of who could win us the most games:
Josh Freeman
Matt Flynn(trade)
Vince Young
Kellen Moore(trade)
Jamarcus Russel
Tyler Wilson(practice squad)
1-3 are all good options in my book.
