One of the underrated elements many don't seem to talk about when it comes to the fantasy football waiver wire is how quickly the gains made via additions there can fade.
Look no further than Adrian Peterson.
AP was one of fantasy football's top adds when he joined the Arizona Cardinals. He put up a monster debut with the team, too, scoring 25.4 points and becoming a matchup-free play for the rest of the season.
He put up 3.3 points in his next game.
The twists and turns aren't always so dramatic, but there is a big reason eventual league winners tend to excel on the wire.
