The main issue I have is your WR. Bolden is a stud, but behind him there are a lot of ?'s. Chambers had a horrendous season last year, so I wouldn't be relying on him for too much production. Bruce is getting old, and they brought in some new weapons on offense that could hinder his production. As for Stallworth, he has potential to be a very good fantasy #2/border line #1 WR, but with the situation that his is in (New England brought in a boatload of talent at WR and has a solid TE in Watson) I think his stats will be down this year. Not to mention he is behind Moss and will be fighting with Welker and Javkson for cathes.
your QB's and RB's are very solid. Landing Brady, Romo, Westbrook, Portis (who i think will have a bouce-back season) is very impressive. Infact, I think you could use either Romo, Taylor, or Peterson in some type of a trade to increase you WR position.
The TE spot is ok with Crumpler, but his level of production will very with the status of Vick. He is by far Vick's favorite target, but if Vick is gone, don't be surprised to see his status flatline.
For D I think Minny is usually a risk, because when they excelle at one area they usually are weak in another. hopefully this year will be different though.
Overall, I think you did fairly solid. I would say a B/B+.
