Any fantasy football manager knows the key to a championship roster is carefully selecting sleepers and next-man-up players among the favorites at each position.
All it takes is a couple of ill-timed injuries for the top of your roster to crumble, and when that happens, you'll need to know you have players on your bench ready to step in.
Sometimes, your sleepers do more than step in. Think about some of the players who were regarded as sleepers in recent fantasy seasons who ended up unexpectedly producing eye-popping numbers: Denver running back Phillip Lindsay, Atlanta tight end Austin Hooper, Kansas City wideout Mecole Hardman.
