I like it, don't love it. I find Team Defense a little plebeian, but IDP adds only a little, not too much, IMO.
[*]Best thing about it, is it attracts more serious, knowledgeable players
[*]I don't like that my best IDP players are often on bad teams. This is especially true of linebackers and safeties, who are either tackling every five seconds because their defense is always playing or making plays because the CB coverage is broken
[*]There's not a ton of variation between players. I play in a small league, and basically, everyone ranks the IDPs by projected points and takes best available. That's all there is to it. Typically, there's one great guy (think Patrick Willis) but then the guys right behind him are also awesome and over the course of the year the differential will be like 5 points, no joke
[*]The scoring gets a little silly...sacks and interceptions have huge point values, often, because otherwise DL and DB would be worthless relative to LB
On a positive note, it does allow more stats to follow!
10 rushing yards - 1 pt
10 receiving yards - 1 pt
20 passing yards - 1 pt
All TDs - 6 pts (QBs favored)
