I think this D is as good/bad as it was in 2014, which was good enough to go 12-4 and catch away from beating GB, mainly because we got turnovers and we kept the D off the field because of the running game.
Does it get better then it is now when Lawrence comes back, will Ryan Davis give us anything, will Nzeocha gives us anything and will the D generate turnovers the way it did in 14. We will see, I hope so but we will see.
With Romo on the field (if he can stay on the field) you will not see 8 or 9 in the box, which should significantly help the running game.
I love what Dak is doing at this point in his carrier, absolutely love it, but there is no doubt who is the better QB at this point in time and there is no doubt which QB D's will respect enough to not load the box at this point and time.
I am not sure why these 2 things are mutually exclusive, I for one am ecstatic that we potentially are seeing our future QB and at the same time he is potentially keeping us in the hunt until Romo comes back. So when Romo comes back, opposing D's will have no idea what to do with this O, load the box and Romo will kill you down the field, play coverage and we will run it down your throat.
IMHO, this potentially is the best of both worlds.
