Every four weeks, we’ll be grading all of the skill-position rookies taken in the first two rounds of the NFL draft in terms of their fantasy relevance and value. Positive marks are awarded not only for stat-line accomplishments, but also for those glimpses of potential that might not earn their owners many fantasy points today, but point to big things to come in the future.

# Week 1-4 Week 5-8 Week 9-12 Week 13-16 Comments
Matt Stafford, QB, Lions 1 C D D His stats were off the charts against the Browns in week 11 (422 yards, 5 TD, 2 INT), and the fantasy world watched to see if he’d turned a corner or was simply the latest QB to abuse the Browns. We’ll take his 1-TD, 4-INT Thanksgiving performance against the Pack to mean that it was the latter.
Mark Sanchez, QB, Jets 5 B C D This marking period started off promisingly (265 yards, 2 TD, 0 INT vs. Miami) but Sanchez quickly reverted back into the low-yardage, multiple-turnover QB we’ve come to expect on a weekly basis.
Darrius Heyward-Bey, WR, Raiders 7 D- D- D He’s got at least one catch in each of his past five games, plus a TD in the last one. When your team’s QB battle is between JaMarcus Russell and Bruce Gradkowski, that’s good for a solid D.
Michael Crabtree, WR, 49ers 10 D B+ B So far, he’s been a remarkably consistent source of 3-6 catches for middle-of-the-road yardage. Last quarter’s speculative B+ might have been a little high for a Niners receiver, but he’s definitely a solid high-end WR3 with upside.
Knowshon Moreno, RB, Broncos 12 B B- A Moreno’s found his stride and is now consistently outperforming backfield mate Buckhalter as well as the rest of the rookie class of RBs. He was a big reason for the Broncos’ victory over the Giants in week 12. The schedule for the rest of the fantasy season is very nice (@KC, @IND, OAK).
Josh Freeman, QB, Buccaneers 17 F D- B Freeman’s been stunningly good for a rookie with only four starts. His 118.5 passer rating in week 12 should give Bucs fans (assuming there are a few still out there) reason to hope for better days in 2010. He’s still only a desperation fantasy start this season, though.
Jeremy Maclin, WR, Eagles 19 B- B B Maclin’s marking period resembled that of classmate Crabtree – commendably consistent if not overly exciting. He might get a chance to shine in week 13 if DeSean Jackson is limited with a concussion.
Brandon Pettigrew, TE, Lions 20 C+ D+ INC Season-ending knee injury.
Percy Harvin, WR, Vikings 22 B+ A A Harvin scored in three out of the past four games and had 146 yards plus a TD in week 12. He’s simply not a normal rookie. What a great pick at #22 by the Vikings.
Donald Brown, RB, Colts 27 B B- D He isn’t getting many carries, and isn’t doing much with the ones he does get. Joseph Addai is the unquestioned feature back on this team, and that doesn’t look likely to change in the near future.
Hakeem Nicks, WR, Giants 29 C- B B See: Crabtree, Michael; Maclin, Jeremy.
Kenny Britt, WR, Titans 30 A- D+ B- This guy’s all over the map. There isn’t a hotter name on the waiver wire this week, but I’m a tad more skeptical than most. Vince Young is working wonders out there, but he’s still anything but a quarterback you can count on to deliver lots of yards and completions. Until that changes, it’s going to be hard to count on Britt as a consistent fantasy option – though he’s definitely an interesting start if you don’t mind high-risk, high-upside types of players.
Chris Wells, RB, Cardinals 31 D C B He’s sort of like Moreno Light – clearly better than the veteran he shares the backfield with. Wells hasn’t looked quite as dominant as Moreno, and his competition (Hightower) is better than Moreno’s (Buckhalter), but he’s obviously the Cardinals’ RB of the future.
Brian Robiskie, WR, Browns 36 F F+ F He caught a ball in the second marking period, but not so in the third. Back to plain old F.
Pat White, QB, Dolphins 44 F F- F+ The Dolphins are letting him touch the ball occasionally in the Wildcat. You should totally start him at QB!
Mohamed Massaquoi, WR, Browns 50 C+ C+ C- He got his piece of the Lions game (115 yards and a score), but who didn’t? Aside from that game, he hasn’t had more than two catches or 30 yards in his past four games.
LeSean McCoy, RB, Eagles 53 B- C- B+ With Westbrook out indefinitely after suffering his second concussion of the season, McCoy’s the man in Philly now. It’s  worrisome that Andy Reid is giving the goal-line work to Eldra Buckley, though.
Richard Quinn, TE, Broncos 64 F F- Seriously, I have no idea who this person is.
