I posted a note under "last night's game" in response to another comment.
But, I wanted to add something. Preseason game #1 is about playing as a team. Individual play is (IMHO) irrelevant. Many players have looked great in game one, only to fall off the roster. The coaches shuffle players to look for the best combinations of players, and look to get the team into a groove. You can't take much away from this game.
Games #2 and #3 are the barometers for the individuals, and we can start to assess where we are as a team. So that's when we'll actually have a sense of great play from individuals and units.
And then game #4 is to fill out the bottom of the roster. Players between about 35-53 are vying for their place on the depth chart, or their very NFL future.
That's my story and I'm sticking to it.
