Receivers are indeed a bit weak. Your strong RBs may counter that, but I'd be looking to trade. May be able to find someone who has a thing for Romo and would rather have him than the good QB he already has (especially if you happen to have a Cowboy Homer in your league). He might do something like his QB and a good WR for Romo paired with one of your current WRs. So basically it would be a strong QB (in his opinion) and a weaker WR from you for his stronger WR and "weaker" QB. Hope that makes sense.... Overall, I'd say you did quite well. Especially for first time.
Whatcha think of these guys
