....and for a more realistic view....
The 99 team had 5 HOF players on it (not counting Holt), had great depth with guys like Az Hakim, Phoehl, Conwell, Holcolm and a very solid D. Heck Winstrom/Agnew/Farr/Carter is not even that far off of this teams starting 4 on the D line.
This current versions O got manhandled by a historically bad Dallas D last year.
