I have no problems saying that the defensive side of the ball is NOT my specialty, but even I can pick out a sleeper defense that is staring me right in the face.
The Seahawks Defense as a whole may not be the strongest, but their running defense has been top notch and underrated all season. Through 12 games, they have given up 16.6 fantasy points to running backs. That's a strong number considering they have had to face 3 top-notch running backs in their division: Steven Jackson (42 rushing yards) and Frank Gore (59 rushing yards). I can't count Beanie Wells because he was out with an injury when the Cardinals faced the Seahawks in Week 3. But you get the point.
The Seahawks get to face a battered Rams offense yet again in Week 14. They were able to hold Jackson in check. And the REAL good news is that not only is Sam Bradford (ankle) not practicing this week, but neither is A.J. Feeley after fracturing his right thumb against the 49ers. That leaved third stringer Tom Brandstater to take all first-team reps in practice Wednesday and could get his first start of the season against Seattle on Monday night. The Seahawks currently rank 12th in the league in terms of fantasy points given up against quarterbacks (19.2). But with Jackson expected to struggle and add in the addition of a very green Brandstater, you could have the makings of a quality start for the Seahawks Defense.
If for some reason they managed to get past by everyone in your waiver wire, snatch them up. They could make for a quality start for Monday night's game. And if things change regarding the status of either Bradford or Feeley, I will update as late as I can.
