No expert here. I have the Jets, the Cards, and the Dolphins. On the wire are NE and Hou who have both been mentioned here. Without bombing you with our league's scoring for defensive teams, it's pretty standard with considerations for fumbles, interceptions and defensive TD's, of course, and points and yardage against. I don't remember which week Oakland changed it's coach, but I went back to week 10. To my surprise, (Scoring systems are relative.) these are the defensive scores each week vs Oakland:
week 10 - Panthers D scores - 17 points
11 - @Miami D scores - 15
12 - @ Denv D scores 3
13 - KC - 15
14 - @ SD - 18
15 - NE - 13
Here's where you have to trust my analysis, but I'm pretty happy with 9 or 10 points, minimally. In my league the top defense (Ravens) this year averaged almost 14 points per week, with the Steelers and Eagles closer to 13. The 12th highest D (Cards) averaged almost 11 for whatever average is worth. The Texans scored a bit more than 8 per week. The bottom team, the Lions, have averaged a tad more than 6 per week. I'm starting to like Houston with its offense clicking vs Oakland. Now do I have the ballz to play them?
