There are always those players who elevate to the highest of highs during the fantasy season but always seem likely to take a dip in the long run—players who become essential adds on the waiver wire but slowly and surely start to lose value.
Maybe an injured player at their position returns, or a backup quarterback doesn't jell with them on the offense. Or maybe a series of easy matchups early in the season inflates their productivity. Whatever the case, there is always a sense with these players that they are about as likely to remain fantasy superstars as Kim Kardashian is to be voted as the president in 2020.
