IMHO I think a lot of last year came down to coaching. Yeah I know players are paid handsomely to produce, but they still need a big kick in the butt, and adjustments throughout the year.
Look at the Giants for instance: IMO one of the best coaching jobs I've seen in years (as much as I hate to admit it!) There secondary was killing them and they had NO consistency on defense. So at the end of the year they adjusted, and sold out on the pass rush. They had no choice, or like us they would have been watching from home. The offense also adjusted to help Eli become more efficient. I think after the Minnesota game last year is when it began. Remember that was the game when he was just throwing up balls and the Vikes D scored 3 TD's. They went to the dink and dunk offense with high percentage passing game, and safe.
My point is they made adjustments, they improved late in the season. Some people say they got "Hot", but the majority of there success came on by coaching adjustments.
That's what we need. I hate the old saying if "it isn't broke, don't fix it line"! In the NFL today you have to be always evolving, and changing. The talent is too similar not to. The only adjustment we made was by running the ball in that playoff game. That was also due to injuries more than adjusting.
We cannot keep staying pat and doing what works, we need to be constantly changing, and experimenting. We have enough talent now to have that luxury. We cannot allow ourselves to get complacent, and stubborn AKA "The Parcell's Way". It's a changing game and the teams that do not adjust will find there teams sitting on the sofa with the rest of us come late January. But that's just my opinion.
