Welcome to the cafe! Its the best FF site around man seriously. And the participation really picks up once things get going.
I like your team. Stud QB, 1 stud RB, 2 stud WR, stud TE, looking pretty good to me. If Mathews ends up being what everyone is saying and expecting then you should do really well. If not then you might be in trouble cause the next best thing you have is Addai.... But hey, every team has some weakness. You should do good, you got that Romo to Witten connection going and you have serious play makers at WR. Good luck!!
