OK beginners, here's how this works: The computer will assign you a set of real-life football players that will make up your team. You will keep your team for the entire season. The players that you are assigned will come from all over the NFL — in other words, the guys on your team will come from a variety of different NFL teams. On a weekly basis, (meaning the Sunday games + Monday Night Football) your team will square off against someone else's and the person whose team accumulates the most points will win the game. The computer keeps track of the statistics, so you don't really need to do anything.
Each team has a roster of players. The idea of the game is that you will plug your best players into the different roster spots, and leave your weaker players in reserve.
(This is where knowing a bit about football is helpful. The more experienced league members will give good, helpful, and sportsmanlike advice.)
In our league each team will have:
1 Quarterback: When your QB throws a touchdown, your team gets 6 points. You also get a point for every 25 yards he throws the ball. If your quarterback throws 3 touchdowns (6 X 3 = 18 pts.) and 275 total yards of passing (275 / 25 = 11 pts.), you would receive 29 total points for the QB position. (Which is a magnificent total!) Although the QB is the most important player in real football, they are not the most important in Fantasy.
2 Running Backs: Every time one of your Running Backs scores a real-life touchdown, your fantasy team gets 6 points! You also get 1 pt. for every 10 yards he carries the ball in a game. If your RB scores 2 touchdown (6 X 2 = 12 pts.) and runs for 160 yards (160 / 10 = 16 pts.), as well as catching passes for 40 yards (40 / 10 = 4 pts.) you would receive a whopping 32 points (12 + 16 + 4 = 32)!!! Because Running Backs typically score the most touchdowns in real football, they are the most valuable players on fantasy teams, and will do the lion's share of the scoring. Every team wants LaDanian Tomlinson, but only 1 will get him. He scores....often.
2 Wide Receivers: 6 pts. for a touchdown, 1 pt. for every 10 yards of receiving. They don't score quite as often as RBs, but they are the next most valuable guys on your team.
1 Tight End: Tight Ends are basically really large receivers. They score the same way as receivers, just not nearly as often. Not a super important position.
1 Kicker: Kickers get 3 points for a field goal and 1 point for a successful extra point after a touchdown. Kickers are fairly random, they all do about the same, and are not important parts of your team.
1 Defense: Each player will be assigned the defensive team of an NFL franchise, and will be awarded points based on how well that defense performs. So, you might get the San Diego Chargers' defense, or the Chicago Bears' defense. If the Bears shut out the team they are playing you will be happy! Nonetheless, defenses perform relatively similarly from one team to the next, so they aren't an important part of your team.
8 Bench Positions: The Bench positions are reserve players who you can put in in case one of your regular starters gets hurt or has the week off. All NFL teams have a free weekend at some point in the season. This is referred to as a "Bye Week." When your best running back is on his bye week, you need to insert your bench running back into the spot for that week, and hope he has a good day.
Trades: People talk about them a lot, but they actually don't happen that often. It's simple: If you want a player from another league member's team, you can offer them one of your players in a trade. If they think it's a fair offer, they might accept.
The Waiver Wire: There are a lot of NFL players, and they won't all be assigned to our teams. These 'leftover' players are available to be added to your team in case one of your assigned players gets severely injured, or just turns out to be a stinker. You can often find great players out there just waiting to be added to your team. This happens most often when a top Running Back or Quarterback gets knocked out for the year, and the second stringer takes their place. In many instances, that second stringer becomes a very valuable commodity and league members will rush to their computers to grab him. At any time you like, you can drop a player and add another from the "waiver wire." This may sound complicated if you have never played before, but it's really simple.
Here are some articles for the new folks that explain how this all works. It's very easy. You can ignore all of the information about drafts, as we are having an auto-pick draft.
