Week 1 is finally here.

After a long offseason spent poring over your pre-draft rankings and crafting your perfect roster, everything should be lining up nicely as we kick off the season.

Of course, that's not how things happen in the fantasy football world.

Drafts go awry. Players get hurt. Guys you expect to start end up buried on the depth chart. Suspensions happen. Your first-round pick decides he's going to hold out. Unexpected hiccups are the norm in this game, and that's why even as early as Week 1, you need to be on the ball in full damage-control mode.

Whether you need someone to plug into your starting lineup for a week or two, or you've got a bench spot open to make a speculative pick-up, it pays to be vigilant on the waiver wire even before the season starts.

Here are eight fantasy football sleepers for Week 1, who you can count on to make an early impact in your lineup.
