It's Week 13 of the 2011 fantasy football campaign, and this week brings with it the conclusion of the regular season in many leagues, making this a do-or-die game for many an IDP owner across the land. To help you prepare for another week's action here's a look at my Top 30 defensive linemen, linebackers, and defensive backs for Week Eleven of the 2011 season in IDP leagues. These rankings are based on Default IDP Manor Scoring, which awards 1 point for solos, .5 points for assists, 2 points each for fumbles forced and recovered, 4 points for interceptions, sacks, and safeties, 6 points for defensive touchdowns, and 1 point for passes defensed. It's a balanced scoring system, so if your IDP league is especially tackle-heavy or big play-heavy some players may move up (or down) a few spots. DEFENSIVE LINEMEN 1.) Jared Allen - MIN vs DEN 2.)
