Really-I think you guys will be fine.
If you ask me, Moss would be a BIGGER loss than Brady.
Pt being that it seems like with the better teams in the league, there's been many times where they've lost their QB, and they didn't miss a beat. It's when they lose their WR/RB...that's where they get into trouble.
It was alot during the Aikman years here in Dallas. When Troy would go down, we wouldn't lose a beat as our capable vets who knew the system came in. However-it was when Emmitt/Irvin went down where the impact would be BIG. Why? B/c without Emmitt, the run game was shot. Without Irvin, whoever was QB, there was no safety valve.
Pt being that the BIG weapons are your RBs and WRs. They can make capable QBs look better than they are. Look at Tony Romo in Dallas. A very good QB, yes. But when you have TWO safety valves in TO and Witten, it's only going to make your job that much easier.
