Wide receiver contributions are hard to predict week to week, which leads to frequent shakeups in the rankings.
If you can't depend on studs like Roddy White, Mike Wallace and Vincent Jackson, who can you depend on?
The answer is no one. You can't depend on anyone at wide receiver because touches and opportunities vary so much.
What you can always bank on is receivers who come seemingly out of nowhere to put up big weeks. Knowing the names of these sleepers is one thing, predicting when exactly they'll go off is another.
Not to worry, we've got you covered. Here are three wide receivers who probably aren't in your starting lineup who will exceed expectations this week.
Jordy Nelson, GB
This guy burst onto the scene in the playoffs for the Pack last season and had a huge impact on the team's run to the Super Bowl. Expectations were tempered this year because many thought he'd be no higher than third on the depth chart at receiver, and that doesn't count tight end Jermichael Finley.
In Week 1, though, Aaron Rodgers called Nelson's number a lot, leading to six catches for a solid 77 yards. What set his performance apart was the TD catch, turning a good game into a great one.
This week, the opponent is Carolina, which isn't exactly a passing retardant. Nelson's role looks to be bigger than most expected before Week 1, which means he could be in for another big game as the slot receiver who gets little attention and coverage from the defense.
Brandon Gibson, STL
The opportunity is there for a relative unknown to pick up the slack in the Rams' receiving corps. Lead men Donnie Avery and Danny Amendola are both down for the count with injuries, so Gibson stands to see a noticeable uptick in targets from Sam Bradford, which has proven to be a nice place to be for a receiver.
This week, the Rams get a Giants team that is falling apart with injury. Cornerback Terrell Thomas went out for the year with a torn ACL during the preseason, which thins out the Giants' secondary. If Steven Jackson doesn't play for the Rams, coach Steve Spagnuolo could turn his attention to the air, which could benefit Gibson's fantasy line.
Davone Bess, MIA
The Houston Texas are infamous for their pass defense; they gave up a league-leading 268 yards per game and 33 touchdowns through the air.
The signing of Jonathan Joseph at corner is a significant upgrade, but Glover Quin and Kareem Jackson are subpar, and Danieal Manning has had better days.
Bess, the consummate slot possession guy, is the one who will fall through the cracks, or draw a poor pass defender. Brandon Marshall, Brian Hartline and TE Anthony Fasano are likely to draw most of the attention, leaving Bess as Chad Henne's safety net.
Bess is not a home-run hitter. He catches short passes and gets a lot of his yards after the catch. He'll get lots of looks against Houston, which promises to speed up the pace and force Miami into the passing game more.
