The sleeper game is relentless.

That's not a cop out; it's just tough sledding.

Some guys -- mainly tight ends -- are touchdown-dependent. Sometimes those guys can get a good red zone look or two but fail to haul it in. Bust.

A wide receiver who could see heavy volume because his team is an underdog? Well, when that team jumps out to an early lead, there goes that idea.

The problem isn't that randomness reigns 100 times out of 100 but rather that the process just doesn't always work like it's expected to.

Plenty of unheralded players put forth surprise performances last week, but not all of them were logical plays (sounds like every week this season, eh?).

I'm not in the game of throwing darts and hoping something comes through, but with that all said, here are 10 guys who make sense on paper -- to varying extents -- who might be in store for a solid Week 6 outing despite some question marks.

You know, sleepers.
