The term “sleeper” has different meanings for different people in the world of fantasy football. Some folks believe it’s simply a player who will outperform his draft position. Others believe it’s someone who was a relative unknown and emerges into a useful fantasy option, such as Tyler Allgeier, Zay Jones or Juwan Johnson.
However, I think there are different levels of sleeper value among NFL players.
For example, a typical sleeper like Rachaad White is likely to come off the board in the middle rounds of drafts. Then, you have another tier. I like to call them the “deep sleepers.” These are the players who have average draft positions (ADPs) in the later rounds who could bring back surprising value.
