The players in this quiz are the all-time leaders in 'Weighted Approximate Value,' a stat PFR created to attempt to give a single number to a player's career contributions.
As the intro says, players who have 90 or more in this stat are the only ones on this quiz--no more, no less. They only go back to 1950, so people like Sammy Baugh and Don Hutson are not here. It also excludes all special teams contributions. Anyway, basically I'm just saying that the players here are NOT random. Just go ahead and start naming players! They are alphabetized.
