NFL football is a team game. Individuals do not win many football games on their own. A total team effort is needed if a team is going to be successful in the NFL.
The team, however, is made up of individuals. There are statistics that are kept for individuals, and based on those stats, some people choose to define the worth of an individual player.
In some cases, the players with the best stats (Dan Marino, Jim Kelly), do not lead their team to the promised land and have a total of 0 Lombardi Trophies in their trophy case. That does not mean that they were not great players, only that the teams that they were on were not the best in football.
Then there are those players that play on great teams. Ben Roethlisberger comes to mind. Because of the talent around him, people are quick to question how great of a player he is based on his stats.
The Hall of Fame does not have a specific criteria for enshrinement. Some players that are in the Hall of Fame have never won a Super Bowl. Many players that have won multiple Super Bowls are not in the Hall.
So, what does a player have to do to be included in the discussion of being Hall of Fame-worthy? And, why are so many people quick to dismiss an individual based on the numbers that are in the record book?
