Jerome Harrison is currently working behind Montario Hardesty during OTAs. Obviously, this is a big blow to those fantasy owners hoping to find a solid RB2 in the third or fourth round in the form of Harrison. This looks like it’s shaping up to be a timeshare. Keep an eye on the competition as training camp wears on. Harrison was outstanding late last season and could be a steal if he wins back the job.

Felix Jones is looking better in the passing game. Jones is unlikely to get enough carries in the running game to become a true fantasy RB1, especially with Marion Barber vulturing goal line carries. But if he can become a regular fixture in the passing game, he could do some serious damage in PPR leagues.

Dustin Keller primed for a big year? The Jets have added some wrinkles in order to utilize Keller’s talents and Rex Ryan has said that Keller is likely to have more TDs than last season (2). He is a solid TE option for those owners who elect to wait on the position and play Tight End By Committee (TEBC).

Domenik Hixon is out for the season with a knee injury. This is a big blow to the Giants’ receiving corps, which will have to lean on Steve Smith and Hakeem Nicks even more this season. Move both players up a couple of spots on your cheatsheet.

Will Eddie Royal bounce back this year? He seems like a prime candidate since Brandon Marshall left town leaving Royal as the best and most proven receiver on the roster. Last year was a disaster, but Royal showed what he can do in his rookie season.

Vincent Jackson prepared to sit out until Week 11. This is bad news for his owners and for Phillip Rivers, but it could be good news for Antonio Gates and Malcom Floyd, who reportedly looks great in workouts.

Cowboys looking to get the ball to Witten in the red zone. He went for 94-1030 last year, but only caught two TD after averaging 5.5 the previous two seasons. If the Cowboys are serious about calling his number more in the red zone, it may mean Witten once again cracks the Top 5 in standard leagues.

In the realm of fantasy football, using early picks on rookies is usually a dicey proposition. It’s not often that a rookie comes into the league and is able to quickly establish fantasy relevance, though a few players do break through every season. Typically, a few running backs make an immediate impact, as that is the easiest position to transition to from college. In 2007, Adrian Peterson and Marshawn Lynch were drafted for the sole purpose of taking over their team’s running game, and they both went on to have successful seasons. Even an undrafted rookie like Ryan Grant can have an impact if he finds the right situation. (I was lucky enough to snatch him off the waiver wire before he went on his 10-game train ride to fantasy stardom. I went on to win the title in that league despite disappointing performances from two of my keepers – Shaun Alexander and Marvin Harrison.)

Last year’s wide receiver crop was a bit thinner. Dwayne Bowe was the top rookie, finishing in the top 20 in most scoring formats. This was an upset considering all the fantasy owners that were drooling over Calvin Johnson’s intangibles before the season started. James Jones and Anthony Gonzalez flirted with fantasy relevance, but otherwise rookie wideouts didn’t make much of an impact in 2007. But every year, it seems like there’s one or two that become starter-worthy. (Who can forget Marques Colston’s 2006 campagin?)

So let’s take a look at this year’s top fantasy rookies and see who’s likely to make an impact.

RUNNING BACKS

1. Jonathan Stewart, Panthers (pictured)
Stewart is a power back and that’s the Panthers’ style. DeAngelo Williams has been something of a disappointment, so if Stewart runs well during the rest of the preseason, it’s not inconceivable that he could earn a starting role. However, durability is a concern with Stewart, so it is more likely that the Panthers will split carries to keep him fresh and injury-free.

2. Darren McFadden, Raiders
Due to his combination of strength and speed, some compare the #4 overall pick to Adrian Peterson. McFadden joins Justin Fargas and Michael Bush in the Raider backfield. Fargas had something of a breakout season in 2007 and Bush is running very well in camp, but McFadden will still get his touches. The team has said they’d like to use McFadden like the Saints used Reggie Bush in his rookie season. Oakland won’t want to wear him out, so this looks like a RBBC for the time being.

3. Matt Forte, Bears
The Bears drafted Forte in the second round to shore up a struggling running game. Cedric Benson was a bust, but the offensive line has been suspect for a couple of years now, so there’s no telling just how much Forte will help Chicago’s ground game. He has looked solid in the preseason, and should be a solid RB3 in most fantasy leagues.

4. Kevin Smith, Lions
Smith is one of the more promising rookies simply because the Lions don’t have any other good options at tailback. Tatum Bell and Brian Calhoun haven’t made their mark, so it’s Smith’s job to lose. He has had durability and character issues during his career, so there is some question as to whether or not he can hold up to the wear-and-tear of a 16-game season. Still, given the lack of competition, he’s an intriguing middle-round fantasy pick.

5. Chris Johnson, Titans
The diminutive speedster seems to be earning a bigger and bigger role as the preseason wears on. LenDale White will get most of the work between the tackles (and, presumably, around the goal line), but Johnson will see a lot of work in the passing game and as a change-of-pace back.

6. Ray Rice, Ravens (pictured)
With Willis McGahee coming off of knee surgery, and Rice impressing in camp, there’s a real possibility that the rookie starts at tailback in Week 1. There are rumblings that the team is none too happy with McGahee’s (lack of a) work ethic, so Rice’s value is enhanced in keeper or dynasty leagues.

7. Rashard Mendenhall, Steelers
The Steelers raised some eyebrows (including Willie Parker’s) when they drafted Mendenhall in the first round. For now, they see him as a complement to “Fast” Willie, but he should eventually turn into an every-down back. The writing is on the wall for Parker; it’s just a matter of time before Mendenhall takes over as the Steelers’ feature back.

8. Steve Slaton, Texans
Ahman Green is hurt. Big surprise. Chris Brown is hurt. Big surprise. Somebody has to carry the ball in Houston and Slaton is second in line after Chris Taylor. Slaton has better speed, but Taylor is a little more physical. If Green and Brown continue to miss time, we might be looking at a Taylor/Slaton RBBC in Houston.

9. Felix Jones, Cowboys
Jones is the “lightning� to Marion Barber’s “thunder,� but this isn’t a timeshare. Barber is the main back, and Jones will be used to spell him and to add some punch out of the backfield in the passing game. Barber owners should definitely target Jones as a handcuff in the late-middle rounds.
