This offseason, lists of the NFL's best players have been all the rage. How about one of the NFL's most irreplaceable payers?
In many ways, the two lists are similar. In order for a player to be irreplaceable, he has to be pretty good. But there are other factors. How important is the player to his team, and what the team would be like without him are both key considerations.
The best NFL teams, such as the Ravens, Steelers and Patriots, have proven that most players are replaceable by letting them leave in free agency. Some players, though, go beyond that general principle.
