I'm going DEEP sleeper - maybe more keeper/dynasty type sleepers.
QB - Andrew Walter - when the Raiders inevitably fall out of contention, watch for Walter to get a look. It's not a coincidence the Raiders passed on Leinart (and no, it's not because of Aaron Brooks either)
RB - Cedric Cobbs - Shanahan has been singing this guy's praise all off-season - he wanted to draft him back in '02, but Belichick beat him to it. He didn't work out in New England, barely saw the field, but he was sought after by Belichick and Shanahan - not too bad of an endorsement, huh? He's the same build and running style of Mike Anderson, and all he needs to be the hottest waiver wire pick up in fantasy is for Ron Dayne to FAIL - anyone think that that is highly unlikely?
WR - Greg Jennings - tough to pick a rookie WR as a sleeper, but I like a lot of things that I've heard about this guy, and with neither Ferguson or Gardner stepping up to fill that WR2 spot in GB, Jennings has to be considered a good possibibility to be starting by the end of the season.
TE - Ben Watson - maybe not as deep as the other guys, but I think this guy is about to break out - last year was essentially his rookie season since he was hurt most of his real rookie season, and now he's a 2nd-3rd year WR/TE - he has WR speed (see him run down Champ Bailey?) and excellent hands. With limited options at receiver this season in NE, I think he's going to become a Ben Coates type safety blanket for Tom Brady.
