Rules

The Basics

There are 17 weeks in the NFL regular season; each week is host to between 13 and 16 games
There are several players in Tigerball; all players for the 2010 season are assigned to the same league / conference: there are not different leagues
Each player selects (predicts; "picks") one team to win each game
Picks must be made and submitted via the Submit Your Picks webpage no later than 10am Sunday morning; for games played on a day other than Sunday, picks must be submitted before the start of the game
There are no points awarded to any team in any game; there is no point spread
Each player receives one win for each victory correctly predicted; total player wins are equal to total correctly-predicted victories
Each player is awarded the points each selected team scores; example: Cincinnati beats Indianapolis 42-3, so each player who selected Cincinnati is awarded 42 points and each player who selected Indianapolis is awarded 3 points
Players who fail to select either team in a game before the deadline (typically at kickoff or 10am Sunday morning, whichever comes first) shall be awarded 0 wins and 0 points for the game

Players compete to lead the league (all other players) in two categories both for each individual week and for the season:
- Wins: these are used to declare weekly winners and the season champion
- Points: these are used for tiebreakers and to determine a season recognition award
At the end of each week, player win and scoring records are totalled and reported on Tigerball.org; weekly totals and current season standings are both reported
The player with the most wins for the week is the weekly winner
Weekly results are listed in order of weekly wins; the week's wins leader is listed first
Current standings are listed in order of season wins; the wins leader is listed first
Points are used to determine a winner in the event of a tie; if there is a tie in both wins and points, there is a tie for the week and both players get credit for a weekly win (just like in the NFL: points act as a sort of regular season overtime, in which there is only one attempt to determine a winner)

At the conclusion of week 17, the Season Champion is determined, and two outstanding players are recognized:
- Season Champion:
  The player with the most wins overall is declared the Season Champion; in the event of a tie, points are the first tiebreaker, weekly wins is the second tiebreaker, and fewest missed games is the third tiebreaker
- Most Valuable Player:
  The player with the most weekly wins is declared Most Valuable Player; in the event of a tie, co-MVPs will be declared
  NOTE: the MVP is the player with the most weekly wins who did not win the season championship
- Offensive Player of the Year:
  The player with the most points overall is declared Offensive Player of the Year; in the event of a tie, co-Offensive Players of the Year will be declared
  NOTE: the OPY is the player with the most points who did not win the season championship nor the MVP
Players are listed in the final standings in order of season wins; the Season Champion is listed first

Playoffs begin immediately following the conclusion of the regular season
The NFL playoffs total 11 games over 4 weeks
Player wins and points start over for the playoffs; playoff results have no affect on season results
Tigerball's playoffs utilize the same rules as the regular season (see "The Basics")
At the conclusion of the playoffs, player wins are totaled and a playoff winner is declared
HINT: there is little margin for error, and the 4 weeks go quickly; historically, losing more than 2 games essentially eliminates a player, so choose wisely
