They weren't the 90's cowboys. However, the lack of quarterback was the issue for Billick...we were just blessed with a great defense, but competent QB play as in executing his plan was important. McNair was competent and Billick got everything left of him.....if McNair was healthy no question we would have won it all in 2006.
13-3 with a broke down McNair. Yes the defense deserves credit....but harbaugh hit 12-4 a couple times with less defensive talent than the Billick era because Joe Flacco is a fairly competent quaterback compared to Boller and Joe Flacco has more arm strength compared to 2006 McNair.
1998 vikings were impressive...points record stood for 10years, period.
