To review the NFL season of 2008/2009, football fans saw the New England Patriots win 18 games in a row; the New York Giants lose their opening 4 games to win out the Wild Card and eventually the Super Bowl, and Randy Moss’ heroics jumping over numerous players to an NFL record 23 receiving touchdowns. How did Patriots owner Robert Kraft build such a highly successful team? The performance of a team’s top players affects the overall winning percentage of the team which in turn affects the attendance of home games. Fans do not care how their team’s individual players may perform as long as their team is winning. That means that even though a team looks good on paper, that it does not necessarily translate to success on the field and as long…show more content…
From each of the eight teams, four of the team’s top performers will be chosen and their number of all purpose yards will be tallied. All purpose yards are tallied by rushing the football (receiving a hand-off for a gain of yards or scrambling as a Quarterback for a gain of yards), passing the ball for a gain of yards, receiving a pass for a gain of yards or returning a punt or kick off for a gain of yards. Because only offensive players have enough all purpose yards to be taken into consideration, no defensive players will appear in the data. To determine a player’s performance, the total number of all purpose yards a particular player has will be divided by the number of games that player has played in. This will determine the average number of all purpose yards that player achieves per game and how important they are to a team’s overall performance. The average all purpose yards statistic for all four players of each team will be added together to form the team’s average all purpose yards per game. This compares the successfulness of a team’s top performers against other team’s top performers, which will equate to the team’s overall record and…show more content…
The eight teams are then ranked again separately based on the total average of yards per game by the team’s top performers. The value in which the team is ranked in each category is then added together and divided by two to show out of the sample of team’s chosen, what theoretical ranking each team should be in if they were the only team’s in the league. Because this method produced answers with decimal numbers and rankings cannot be in decimal points, the team’s overall performance ranking trumped the team’s average home attendance ranking. For example, the Tennessee Titans were ranked second in the sample’s average home attendance and fifth in the sample’s average player performance. At the same time, the New York Giants were ranked third in the sample’s average home attendance and fourth in the sample’s average player performance. Using the equation mentioned earlier that mean both team’s theoretical ranking would be 3.5. However, since the fan’s who attend games do not actually play in the games, New York had better player performance and was in fact the better football team and should have been ranked higher than
