Andre will be out at least a few more weeks, and I'd bet, if they're winning that they'd sit him till after their bye in week 11. DeSean is the ultimate streaky guy, he's either going to get you 25+ or 5.. AJ is the only piece you're getting that I really like. You'd be giving Romo who's a great fantasy QB, Gore who's a stud RB, and Marshall, who may not get the TD's but he will get yardage and catches if its a ppr league.
I dont really like this deal for you, there's got to be a team that needs a QB, I'd try shopping Cam though, I think all the reasons people werent as high on Vick at the start of the year apply to Cam as well.
I just think he should look for a better deal, he's trading for a WR that when he's out there is one of the best, but he himself said yesterday that it should be a 6 week recovery. He doesnt help him right now, and may not be able to help him till week 12. DeSean is good when he's good, but he relies heavily on the deep ball and the philly o line isnt giving Vick much of a chance. AJ like I said is solid and I do like that aspect.
I would just shop both QB's, you definetely need to make a move for a WR, I just don't like giving up a stud QB, stud RB, and a very solid WR2 for an injured WR1, a streaky boarderline WR1/WR2, and a rookie who does have a tougher schedule coming up along with colder weather.
I would prefer to keep Gore, so if he'd do something like Romo/Marsall for Andre/AJ I'd do that or even Cam/Marshall for Andre/AJ.
