I don't do this trade either.
For one thing you've got 3 stud WRs and Titus Young who I think will be a stud, so you don't *need* Bowe.
You have Romo and Ben so you don't *need* Rivers, and I also love Locker's longterm outlook, even if Hasselbeck opens the starter I don't think he finishes the year the starter and Locker will be a stud in 2013.
Giving up Matt Forte messes up your excellent depth at RB, which is crucial with so many flex spots. (Yeah you get Helu but I *HATE* Shanihanigans). I think the addition of Michael Bush is slightly overblown, Mcfadden was still a stud with him there and I think Forte will be too. People thought his value was going to take a big hit with Marion Barber and it didn't, I think Bush gets a Barber-esque workload, not a 50/50 split or anything like that. Forte is still a top 10 back in my book.
Also I'm not entirely sold on Jared Cook so I like having Fred Davis around still, I think he is being undervalued because his year-end stats took a hit with the suspension but his per game stats were elite last year, and while there's more weapons there he also has a humongous upgrade at QB and will probably see more sustained drives and scoring chances with a better offense.
