Well, after last night's performance, you should be 1-0. Brady (insane numbers) and Marshall had a good night.
Your team is solid. I don't like Ward this year at all, and you don't have the depth to replace a flex with a RB. Your weakness is RB, but Forte and Hightower should be fine as RB1 and 2. If you wanted to trade down on Brady, after last night's performance, you could probably get a stud RB plus a good QB.
Overall, your team should easily make the playoffs though. For 12 team, this is a very solid squad.
I think your team looks pretty good. I'd say you could use a bit more help at RB and I'm not sold on McNabb having a good season and so I'd see if there was a better back up then him on the wire. I agree with the other poster, you could trade down from Brady, like to Schaub or Big Ben, and for a big time RB.
Brady is obviously a great QB, all though I'm not thrilled with your RB's. Forte and Hightower are OK #1/2 but you have no depth there and it hurts you a little that you are in league that starts 2 at the flex. Your WR's are very nice though, although I don't think Ward will have a good year so he will hurt you a little as your 2nd flex option. It is a shame that you can't make trades in this league as I think you could really improve your team by trading one of your WR's for a RB. However for a 12-team league I think that are you in nice shape and have a good chance to make the playoffs.
