Welcome to the world of IDP. First off, my advice to new IDP owners is that make the Defensive scoring significant enough that they matter or else it tends to just be like having kickers.It is really hard to replace a Ray Lewis or London Fletcher, because you are not exactly sure if the coaching staff/front office is going to replace him with one guy or a combination of players (ie player for passing downs and one for running situations). This is why you hear he is a 3-down player a lot. The more you are on the field the better chance you can score more points. Also, keep in mind that good IDPs are not exactly on good defenses (in some cases they may not be good defensive players at all). A good example are average to below corners that play opposite good corners, they get points because the ball is thrown their way more so they have more tackles or pass defended.With all that said, here are some guys that might fit the mold you are talking about. Some of these guys are coming off injury so might be under valuesKelvin Sheppard, MLB, BillsPat Chung, S, PatsCarlos Dunlap, DE, BengalsDre Kirkpatrick, CB, BengalsJames-Michael Johnson, LB, BrownsStevenson Sylvester, LB, SteelersDerek Cox, CB, JaguarsNate Irving, LB, BroncosDonald Butler, LB, ChargersPerry Riley, LB, RedskinsJasper Brinkley, LB, VikesAkeem Dent, LB, FalconsBobby Wagner, LB, HawksThese list is by no means complete, but should be so good value guys to look for. Remember just because they start does not even mean they are getting 50% of the snaps so keep an eye on them.
I apologize if this is already posted somewhere...I've been playing FF for over a decade but I'm very new to IDP. I'm now familiar with top tier guys at each position, but who are the guys 'waiting in the wings' so to speak? I'm assuming there are supposed replacements/players stuck on the depth chart for guys like Ray Lewis, Ed Reed, Charles Woodson, London Fletcher, etc, and while said guys might not be redraft worthy, I'm trying to help folks in dynasties out (such as myself) for 2013 and beyond. Any lists/advice appreciated. Thanks!
