Quarterback
Joe Webb, Minnesota: I am assuming many will keep him in larger dynasty leagues, but in shallower leagues, he could be available. Favre is done, and Tavaris Jackson is uninspiring. Anytime you can get your hands on a qb with wheels, it is worth a flier.
Josh Johnson, Tampa Bay: One of the better young backups, IMO. Johnson is a mobile qb who needs an opportunity.
Running Back
Steve Slaton, Texans: Pretty good chance he is cut by the Texan, and that will be the best thing for him. A year removed from his neck injury, Slaton is a very good runner and receiver, who fell into the doghouse due to a fumbling problem. With an opportunity, he can be extremely valuable.
Deji Karim, Jacksonville: Compact rookie has been impressive in spots. Could pass Rashad Jennings on the depth chart.
Danny Ware, Giants: With Brandon Jacobs likely moving on, Ware will be asked to step in to fill the void. He has produced when asked.
Wide Receiver
Andre Roberts, Cardinals: The transition from small college school to the NFL is a big leap, and it showed in camp. He has great raw skills, and has improved each game he has been in. Great target.
Seyi Ajirotutui, Chargers: Speed, opportunity, and elite qb. Sometimes thats all one needs to be fantasy relevent.
Tight End
Travis Beckham, Giants: Awesome receiver. All he needs is a starting gig to produce TE1 numbers. I am very high on him.
