IDP STUDS AND DUDS: Week 9 IDP Start/Sit We've entered the second half of the 2011 fantasy football campaign, and as we near the stretch run every game, and every lineup decision, becomes that much more important as teams jockey for playoff positions or try to scratch and claw their way back into contention before their season slips away. Remember, this is the next to last of the bye weeks, so if you roll out any players from the Panthers, Lions, Jaguars or Vikings you likely won't be pleased when they get you a big fat goose-egg. That said here's a look at some players you should give serious consideration to getting into your lineups or who could outperform expectations (Studs) and some that, for whatever reason, you may want to consider leaving alone, or at least take into account that they may be a relative disappointment this week (Duds).

Larry Foote -- ILB, Pittsburgh Steelers (vs. BAL): With the Pittsburgh LB corps decimated by injuries the 31 year old Foote steps into an every down role inside and has a favorable matchup this week with the hated Ravens. Daryl Washington -- ILB, Arizona Cardinals: Only two teams in the National Football League allow more fantasy points per game to opposing linebackers than the Rams, so the second-year pro should be in for a solid outing in Week 9. Marcus Gilchrist -- CB, San Diego Chargers (vs. GB): With cornerbacks it's all about matchups in IDP, and the matchup doesn't get much better than the buzzsaw that is the Green Bay Packers offense.
