QB: Schaub, Rodgers - both have the tools to put up some big numbers and aren't very high on the rankings. The problem is that both have durability issues as well. I would prefer to have Schaub over Rodgers because you can handcuff Schaub with Rosenfels and be confident of good production based on what Sage was able to do after Schaub got hurt last year.
RB: There aren't many RBs that you can really call sleepers. Everyone knows about the RBs that are out there. I like these guys' chances to put up some decent numbers if they can get on the field on a consistent basis - Slaton, Norwood, Lorenzo Booker. I would love to put Pierre Thomas in that mix, but I don't think the Saints coaches see as much in him as all of the fans do. If Deuce gets hurt, Pierre will likely see the goalline touches, but that will only be enough to make him valuable as a flex player at best since the Saints are going to employ a fairly even RBBC no matter what happens.
WR: Kevin Walter, Robert Meachem, Ernest Wilford. Walter because he played well when Andre Johnson was hurt, and I think they will be able to spread it around enough that Walter can have some good games even without an AJ injury. Meachem because he could be the guy consistently facing single coverage opposite Colston and Shockey (you have to watch training camp reports, though, because he may not win that starting job - it's a better pick in a keeper/dynasty). Wilford because he has been a TD machine in a crappy offense before. I think that MIA will find a way to generate some production, and I don't have confidence in Ginn's ability to be the go-to guy at receiver.
TE: Crumpler, Dustin Keller. Crumpler because he has been very good in the past, and VY is going to lean on him. Keller because he plays the type of game that yields good fantasy TEs, and I think that NYJ wants to create mismatches with him. The guys that are mismatched are the guys that score TDs.
K: just kidding. I'm not picking a sleeper kicker.
