I am not familiar with the ADP of defensive players in a league like this, but just looking I would say that you drafted a few of them fairly early and that probably cost you RB depth. It looks like you can start 3 and you only have 3. What round did you draft Brady? I probably would have taken a RB with that pick depending on who was available.
