I was surprised at how bad the Bears D ended up being. I really thought they'd keep the Colts in better check, maybe even sack a few times. I'm thinking the Bears might need a new QB.
I think that the telling factor of why the Bears D performed as bad as they did was when they showed the total Indy plays at 64 and the total Bears plays at 24... When your defense is on the field for that long, you can't expect them to do very well, especially late. I agree though, I thought that they were going to have a much easier time stopping the run than they did. I'm looking forward to next year when they get Tommy Harris and Mike Brown back. They also need to make sure that they keep Briggs next to Urlacher for a long time...
As far as Rex is concerned, I take him for what he 'technically' was this season, a rookie quarterback with a lot more to learn. This was his first full season at the helm and he was able to help get them to the Superbowl. If he can work on his weaknesses in the off-season and work with Ron Turner to develop a more diverse offensive attack, I think that they will be in good shape again next year.
Congrats to the Colts, and Tony Dungee. It's been a long time coming.
