Thus far in the 2009 season, some rookies have disappointed, others have come out of nowhere to become stars, and others have lived up to high expectations. Position wise, rookies have made the most impact at wide receiver, with speedsters like Percy Harvin and tall guys like Kenny Britt. Here's a look at the top 5 rookie performers thus far.

No. 5 Matthew Stafford, QB, Lions

So far Stafford has been wildly inconsistent, but with the Lions all you have to do is win one or two games and you're improving. However, Stafford has looked like a leader and is improving. So far he's recorded three touchdown passes and six interceptions.

No. 4 Percy Harvin, WR, Vikings

Harvin was touted as the most electrifying athlete in last year's draft, and righfully so. He's already one of Brett Favre's favorite targets and scored on a kickoff return against San Francisco. So far he has 167 receiving yards, 410 kickoff return yards, and 28 rushing yards.

Johnny Knox, WR, Bears

Knox has come out of nowhere to be the Bears go-to guy. Despite being overshadowed by other draftees like Juaquin Iglesias in the preseason, Knox has 190 yards receiving in a potent Bears offense.

No. 2 Mark Sanchez, QB, Jets

Sanchez has the Jets headed in the right direction and hasn't looked like a rookie so far, leading the Jets to a win over New England. He's accounted for 5 touchdowns and thrown five interceptions. Three of those interceptions came against New Orleans.

No. 1 Kenny Britt, WR, Titans

Britt has looked absolutely top-notch so far, and will be a star for many years to come in the NFL. He can beat any corner with his size but can move surprisingly fast for a big WR. He has been a bright spot on a struggling Titans team.
