Did you ever play football or any sport at a high level?
I ask because new people thrust into playing time are prone to mistakes. New coaches with new players under this silly new no-practice / no-preseason climate are likely to have a hard time including getting their players tight and right.
I haven't seen the first bit of unmotivated play. The whole idea you can tell what's going on in someone's head from inside a helmet or even by their facial expression is stupid. Some people are loud and easy to read. Others are not. In the face of conflict, the guys like Brees and Manning who look like surgeons and whose pulse rates stay at 54 are the guys who perform best under pressure.
