just google it until you cna find a site that talks about IDPs i guess. i've been looking for one to. Defense is tough cause one day a guy cna ahve 10 tackles, the next he'll have 4. Interceptions are a chance thing. Two weeks into the season, your best bet is looking at guys who have consistently put up decent fantasy points. Wiht my defense I like consistency as muhc as possible. I prefer linebackers over d-linemen if that's an option for you. Instead of picking cornerbacks, you're better off with safeties just cause they're more likely to blitz, stop runs, and pick off those deep hail mary bombs. But like anyhting else, it's alot of luck. If brackett is still around he's a good pickup at linebacker (plyas for indy). Two weeks in a row he's put up over 10 points which i consider to be a decent day.
