You could also say the 99' team, specifically the defense, imploded in 2000.
The 99' team was a great Ricky Proehl catch away from losing to Shawn King! So I would hold up on the game management QB line.
Yes, it could be said the 99 imploded in 2000. Defensively. The offense was actually better statistically, except for the picks. Can we determine what happened to the defense, that made them so bad in 2000? Did they lose a lot of players? No. They lost a coach by the name of Bunting, who was co-DC with Peter Giunta. And then Giunta was scape goated and Lovie Smith was hired.
The bottom line is this. The 99 team did have an easier schedule than the 2001 team (or 2000 team for that matter). But once the playoffs arrived that goes out the window. They put up 49 on Minnesota, with their first postseason snap in a decade going 77 yards for a TD. They beat the snot-popping Bucs 11-6 in the defensively battled CCG. Then they beat the Titans in the SB after blowing a 16 point lead, the first play (again) after Tennessee tied the game went 73 yards for a TD. They got the job done. Period. People can put any disclaimers on it such as easier schedule, great catches, etc. etc. but the bottom line is, they brought home the trophy.
The 2001 team, while talented and vs a tougher schedule, didn't bring it home. Disclaimers can be put on their performance too. Such as, they were lucky the Eagles took care of Tampa and the Saints didn't make the postseason, because Martz, with any version of the Rams couldn't beat the Saints (2-4) or Bucs (1-3). They got Green Bay and Favre, who threw 6 picks in the game. Always the gunslinger, his response to being down was throw it up for grabs. The next game (Philly) they squeaked by, thanks to a McNabb fumbled snap to start things off on their first series, just like he started things off on their first series in week 1. And then they faced the Patriots, who were introduced as a 'team' while the GSOT were introduced individually all the way up to Ricky Proehl looking into the camera and saying, "a dynasty is born tonight". How fucking prophetic!!!!
When you look at the list of Superbowl Champions the 2001 team is nowhere to be found and the 1999 team doesn't have an asterisk that indicates an easy schedule. In fact, the 99 team is remembered for being one of the most amazing teams in history. Cinderella QB, Marshall, Marshall, Marshall, Ike and that rookie, TGSOT, an opportunistic defense, unequalled special teams with Money, Az and Tony Horne led by a head coach who kept it all together. Hollywood loved them!
