1. Alshon Jeffery, CHI
Assuming Jay Cutler signs an extension to stay with the Bears, Jeffery has the greatest keeper value. Catching balls from a top quarterback and a top wide receiver—Brandon Marshall—occupying the defense's No. 1 cornerback, Jeffery can have a very productive career.
With a wide catch radius and the size to be a force in the red zone, Jeffery can both contribute as a rookie and in the years to come.
2. Justin Blackmon, JAX
While not an elite prospect like a Calvin Johnson, Blackmon is a very dangerous receiver in the mold of a Hakeem Nicks.
Blackmon's success hinges on former first-round pick Blaine Gabbert, who was bad as a rookie. Gabbert's play last year could mostly be attributed to a horrific receiving corps, so Blackmon has a chance to bring the best out of Gabbert.
3. Michael Floyd, ARI
Reports so far are that Floyd is out of shape, which is cause for concern. Questions are also allegedly being raised about his work ethic and quickness.
That could end up being nothing, or it could signal some red flags.
Add that to troubling quarterback play in Arizona from Kevin Kolb/John Skelton, and it makes one pause before heartily drafting him as a keeper.
4. Kendall Wright, TEN
With Kenny Britt's recent DUI arrest, Wright's keeper value bumps up a bit.
It's unclear what will happen to Britt but a suspension is likely. Wright, in turn, is likely to see the field more often this season, and nothing beats on-field experience.
Britt becomes a free agent after 2013, and Wright could develop into a major force by then with Jake Locker.
5. Mohamed Sanu, CIN
Cincinnati suddenly has a lot of mouths to feed.
Between A.J. Green, Sanu, Jermaine Gresham, rookie tight end Orson Charles and rookie receiver Marvin Jones, emerging quarterback Andy Dalton has a lot of options.
Rumors have Sanu on track to win the starting job opposite Green.
He certainly has the skill set to do so and be very productive, especially in PPR keeper leagues.
6. Rueben Randle, NYG
Randle is a talented player on a strong offense with a top quarterback. He may not produce much this year as a rookie, but I like his keeper prospects long-term. He ranks behind Sanu because Randle is the third option behind studs Hakeem Nicks and Victor Cruz.
Best of the Rest
A.J. Jenkins has big upside, but is mired in a tough situation in San Francisco with Vernon Davis, Mario Manningham, Michael Crabtree and Randy Moss also demanding the ball. Jenkins' rookie prospects are dim, but perhaps he can rise above the other receivers in a couple years.
Brian Quick is another talented player, though a bit raw and unpolished. His quarterback, Sam Bradford, is also a bit of an unknown quantity. The Rams offense in general has a long way to go, and if Quick becomes the team's No. 1 receiver, he will be facing opposing defenses' top cornerbacks. It's not an ideal situation and one I'm wary of.
Stephen Hill has off-the-chart measurables, but that doesn't always translate to fantasy production, especially when Mark Sanchez is your quarterback and the dysfunctional Jets are your team. Hill certainly doesn't project to be relevant for fantasy as a rookie, but the Jets offense just isn't fantasy-friendly enough to remove cynicism about Hill's fantasy relevance as a keeper either.
