Chiefs and Bears for real?

After three weeks, how serious do you take the Kansas City Chiefs and Chicago Bears? Most experts predicted an improvement for both teams, but certainly not to this extent. I know it's still early, but teams that start the season 3-0 have a much greater chance of making the playoffs than those who don't. We also know the nfl is notoriously kind to the underdog. Every year, a cellar dweller from a year ago makes the playoffs. Do I believe? At this point I have to. The New Orleans Saints are the reigning champions. If the expert preseason predictions were correct, then the Chiefs and Bears have combined to knock of San Diego, Dallas, San Francisco, and Green Bay. Four teams that were all picked to win their divisions. Can the Chiefs and Bears pull this thing off and play for it all? The next 14 weeks will answer that question. True reality tv.
