It's a term tossed around liberally in pre-season (and even mid-season) fantasy rankings. "David Johnson is a guaranteed RB1 this year," "Zach Ertz could be a sneaky low-end TE1 in 2017." But who did and didn't live up to that ranking this year?

To make sure our terminology is clear, a WR1 is a wide-receiver who ends the season in the top 12 in total fantasy points scored (as the standard fantasy football league has 12 teams). Therefore, by definition, there can only be 12 “Ones” at every position. Every year there are some surprising and not-so-surprising faces on the final list of Ones, so it can be interesting to see the journey each player took to end up in the top 12. Some start out incredibly hot before coming back to earth the second half of the season (hey there Kareem Hunt). Some are in second when their suspension hits, but still finish strong enough to end up as the tenth overall running back — even having missed six weeks — (lookin' at you, Ezekiel Elliot).
