Every week in fantasy football, there are unknown players that shock us with huge performances, good players who surprise us with great weeks, those that simply perform as expected and, of course, the week's major disappointments.

In this article, I'm only interested in the first two categories.

Are there good players who I think will come back to Earth this week? Sure. I don't expect Matt Ryan, Robert Griffin III, C.J. Spiller or Kevin Smith to put up such big numbers moving forward, but I think they'll maintain their fantasy relevance. Heck, I think Kevin Ogletree will too.

However, some players, well, I just can't get behind their huge performances from Week 1. Let's call out the one-week wonders.

If you think for one second that Gabbert will make a habit of registering 18 fantasy points a week, well, I question whether you've actually seen him play. You may think I'm being mean, but I'm just trying to look out for my fellow fantasy owners.

Please stay away from Blaine Gabbert. Please.

Shonn Greene, New York Jets

Greene had 15 or more fantasy points just three times last season. Despite a solid first week, I expect he'll return to fantasy irrelevance outside of the deeper leagues once again this year. I'm not fooled by his Week 1 breakout, and you shouldn't be either.

Things I feel comfortable predicting:

• The Jets won't score 48 points again this season.
• Stephen Hill won't have many weeks like his five-catch, two-touchdown and 89-yard performance on Sunday. 
• The Steelers will remind all of us that the Jets offense isn't terribly good this weekend.

In deep leagues or those of the keeper variety, I like Hill as a pickup for those who can afford to stash him and see how his season plays out. However, I don't think you'll see many more weeks like this one.

I like Moore a lot. Always have. However, I don't think you can expect him to catch six passes for 120 yards and a touchdown most weeks. I certainly don't think you can expect him to receive 11 targets each week.

The simple fact remains that when it comes to fantasy receivers on the Saints, you can only really trust Jimmy Graham from week to week.

Two words: Mike Shanahan.

Two more names: Roy Helu and Evan Royster.

Two final thoughts: Morris may have rushed for 96 yards against the Saints, but he averaged just 3.4 yards per carry. He's valuable as long as he stays the clear starter, but we all know how unlikely that is.
