I'm going to add something I haven't seen mentioned that I think is an important factor.
Team psychology. I believe there exists a team psychology, an unvoiced yet present emotional state in the team as a group that has a major effect on how they play. Ideally, an emotional cohesion develops in a football team in which they themselves believe in their own ability to win football games. Last season I think this element was missing in the Redskins-the team didn't display any confidence in itself after a dismal start against weak teams, locker room dissension, uncertainty about how the team was being run and coached, and an increasingly restless and angry fan base complaining loudly and constantly. A team that believes in itself stands a much better chance of winning football games than a team that does not, I think. I am encouraged by what seems to be signs that the team-as a team-has bought into the new coaching staff, new offensive and defensive systems, and, at least publicly, are displaying almost to a man a sense of self-confidence and in some cases seeming actual excitement about getting out on the field and playing that wasn't present last season.
My sign of progress here would be the continuing of this trend toward a positive team identity whether we win 6 games or 10. The fact that I have seen signs of this is what caused me to go for an 8-8 season prediction in spite of the many questions that still exist about the coaching, systems, THE major internal distraction, personnel changes, and the wide spectrum of fan expectations I've read. If the team keeps and improves upon the "new" perspective I'm detecting, then we will indeed, I believe, not have another debacle of a season like last year-we will win some games against good NFL teams which will serve to add extra energy to the team's confidence in itself. The players, after all, are the ones going out on the field doing the job and belief in your ability to do that generates success. I would measure success, among other things of course, as the continuation of this shift in how the team feels and the maintaining of this direction change.
