NFL player rankings are a tricky thing. Quarterbacks tend to dominate because they play the most important position on the field. Extra attention needs to be paid to offensive linemen since they don’t have the ready-stats like the skill positions. Then there is the question of best based on the previous year or over the career of a player. There is a whole lot of subjectivity that goes into such an exercise and no two people will ever fully agree on a list.
Given that, it still can be an interesting tool to see how neutral observers view a team.
