Teamwork. It's a fundamental piece of the puzzle for successful football teams. We've seen what can happen when players buy into the message (the New England Patriots circa 2000-present) and we've seen what can happen when they don't. Of course, getting a group of people to work together and communicate effectively is always easier said than done and if you've ever played any type of squad-based first person shooter with random strangers, you know what I'm talking about. Thankfully, playing cooperatively in NFL Blitz isn't nearly as painful, but the fundamentals are still important. Even though you might only be dealing with one teammate, you'll still need to communicate to have success against your opponents.
