The D was ill-disciplined. So many penalties that kept the Dolphins drives alive giving them 1st downs by encroachment on a 3rd and 4....(I think we had something like 10 penalties). The Dolphins played conservatively in the 1st half, but adjusted well in the 2nd half and played much better than the Bills. Byrd made an unbelievable pick. Otherwise, that would have been a long gain.
I agree that the D played well in the 1st half, but was a no show in the 2nd half until a great play by Byrd and a stupid throw by the Miami rookie QB (on the last drive).
I think it is you who needs to get real.
