I used the Chiefs this week...I backed out of picking the Chargers, and for a while it looked like that might have been a wise choice...I bet people who picked the Chargers were sweating out that game.
On a side note, what happens if there are still people left playing when the regular season ends, and you have already picked all the playoff teams? Does the game reset for the playoffs for everyone that's left, or are you just eliminated if you can't make a pick?
