Debates about who the best player is at a certain position are an exercise in subjectivity. Rarely will there ever be widespread agreement (not that it hasn’t happened before), no matter what the position is — all that one can do is make the argument for a given player.
Kicker, conversely, is one of those positions in football that has had more of a general agreement regarding who the top dog is, with Baltimore’s Justin Tucker holding that symbolic crown for a number of years at this point. With Tucker missing a kick in each of his last three games, however, that crown is just waiting for someone else to take it.
